* disambiguate Bootmagic rules in keymaps

The files edited by this commit were added at a point in time where `BOOTMAGIC_ENABLE = yes` enabled full Bootmagic.

This commit edits the files to specify that full Bootmagic is intended.

* remove BOOTMAGIC_ENABLE=full setting

* unify commented BOOTMAGIC_ENABLE rules in keyboards

Explicitly sets `BOOTMAGIC_ENABLE = no` in keyboards where the rule was commented out.

Command:

```
find keyboards/ -type f -name 'rules.mk' -and -not -path '*/keymaps/*' -exec sed -i -e 's;#[ \t]*\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-zA-Z]\+\).*;\1 = no       # Virtual DIP switch configuration;g' {} +
```

* remove commented Bootmagic rules from keymap/user level

Command:

```
find keyboards/ layouts/ users/ -type f -name 'rules.mk' -exec sed -i -e '/#.*\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-z]\+\).*/d' {} +
```

* update keyboard BOOTMAGIC_ENABLE rule formatting

Sets the formatting of BOOTMAGIC_ENABLE rules to `BOOTMAGIC_ENABLE = [value]`, without the inline comments (which will be replaced later).

Command:

```
find keyboards/ -type f -name 'rules.mk' -and -not -path '*/keymaps/*' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-z]\+\).*;\1 = \2;g' '{}' +
```

* update keyboards' BOOTMAGIC_ENABLE settings

Updates keyboard `rules.mk` files to use `BOOTMAGIC_ENABLE = lite` where `BOOTMAGIC_ENABLE = full` was being used.

Command:

```
find keyboards/ -type f -name 'rules.mk' -and -not -path '*/keymaps/*' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE = \)full;\1lite;g' '{}' +
```

* update keymap/user BOOTMAGIC_ENABLE settings

Updates keymap/user `rules.mk` files to use `BOOTMAGIC_ENABLE = lite` where `BOOTMAGIC_ENABLE = full` was being used.

Commands:

```
find keyboards/ -type f -name 'rules.mk' -and -path '*/keymaps/*' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE[ \t=]\+\)full;\1lite;g' '{}' +
find layouts/community/ users/ -type f -name 'rules.mk' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE[ \t=]\+\)full;\1lite;g' '{}' +
```

* remove and replace inline comments in keyboards and keymap/user files

Removes and replaces the inline comments, which have been updated to read `Enable Bootmagic Lite`.

Commands:

```
find keyboards/ -type f -name 'rules.mk' -and -path '*/keymaps/*' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-z]\+\).*;\1 = \2;g' '{}' +
find layouts/community/ users/ -type f -name 'rules.mk' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE\)[ \t=]\+\([a-z]\+\).*;\1 = \2;g' '{}' +
find keyboards/ layouts/community/ users/ -type f -name 'rules.mk' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE = lite\);\1     # Enable Bootmagic Lite;g' '{}' +
find keyboards/ layouts/community/ users/ -type f -name 'rules.mk' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE = yes\);\1      # Enable Bootmagic Lite;g' '{}' +
find keyboards/ layouts/community/ users/ -type f -name 'rules.mk' -exec sed -i -e 's;\(BOOTMAGIC_ENABLE = no\);\1       # Enable Bootmagic Lite;g' '{}' +
```

* rename improperly named makefiles

Some files intended to be used as makefiles had improper names causing them to not be used as intended when building.

This commit corrects the filenames of the affected files.

* update renamed file with new rule formatting

* update QMK's template files

Updates QMK's `rules.mk` templates to use the new inline comment.

* Update ADC driver for STM32F1xx, STM32F3xx, STM32F4xx (#12403)

* Fix default ADC_RESOLUTION for ADCv3 (and ADCv4)

Recent ChibiOS update removed ADC_CFGR1_RES_10BIT from the ADCv3 headers
(that macro should not have been there, because ADCv3 has CFGR instead of
CFGR1).  Fix the default value for ADC_RESOLUTION to use ADC_CFGR_RES_10BITS
if it is defined (that name is used for ADCv3 and ADCv4).

* Update ADC docs to match the actually used resolution

ADC driver for ChibiOS actually uses the 10-bit resolution by default
(probably to match AVR); fix the documentation accordingly.  Also add
both ADC_CFGR_RES_10BITS and ADC_CFGR1_RES_10BIT constants (these names
differ according to the ADC implementation in the particular MCU).

* Fix pinToMux() for B12 and B13 on STM32F3xx

Testing on STM32F303CCT6 revealed that the ADC mux values for B12 and
B13 pins were wrong.

* Add support for all possible analog pins on STM32F1xx

Added ADC mux values for pins A0...A7, B0, B1, C0...C5 on STM32F1xx
(they are the same at least for STM32F103x8 and larger F103 devices, and
also F102, F105, F107 families).  Actually tested on STM32F103C8T6
(therefore pins C0...C5 were not tested).

Pins F6...F10, which are present on STM32F103x[C-G] in 144-pin packages,
cannot be supported at the moment, because those pins are connected only
to ADC3, but the ChibiOS ADC driver for STM32F1xx supports only ADC1.

* Add support for all possible analog pins on STM32F4xx

Added ADC mux values for pins A0...A7, B0, B1, C0...C5 and optionally
F3...F10 (if STM32_ADC_USE_ADC3 is enabled).  These mux values are
apparently the same for all F4xx devices, except some smaller devices may
not have ADC3.

Actually tested on STM32F401CCU6, STM32F401CEU6, STM32F411CEU6 (using
various WeAct “Blackpill” boards); only pins A0...A7, B0, B1 were tested.

Pins F3...F10 are inside `#if STM32_ADC_USE_ADC3` because some devices
which don't have ADC3 also don't have the GPIOF port, therefore the code
which refers to Fx pins does not compile.

* Fix STM32F3xx ADC mux table in documentation

The ADC driver documentation had some errors in the mux table for STM32F3xx.
Fix this table to match the datasheet and the actual code (mux settings for
B12 and B13 were also tested on a real STM32F303CCT6 chip).

This converts the array that the Swap Hands feature uses to use PROGMEM,
and to read from that array, as such. Since this array never changes at
runtime, there is no reason to keep it in memory. Especially for AVR
boards, as memory is a precious resource.

* Fixup housekeeping from being invoked twice per loop. (#12933)

* matrix: wait for row signal to go HIGH for every row (#12945)

I noticed this discrepancy (last row of the matrix treated differently than the
others) when optimizing the input latency of my keyboard controller, see also
https://michael.stapelberg.ch/posts/2021-05-08-keyboard-input-latency-qmk-kinesis/

Before this commit, when tuning the delays I noticed ghost key presses when
pressing the F2 key, which is on the last row of the keyboard matrix: the
dead_grave key, which is on the first row of the keyboard matrix, would be
incorrectly detected as pressed.

After this commit, all keyboard matrix rows are interpreted correctly.

I suspect that my setup is more susceptible to this nuance than others because I
use GPIO_INPUT_PIN_DELAY=0 and hence don’t have another delay that might mask
the problem.
