[Keyboard] Pinky refactor (#11643)

* QMK Configurator layout support for Pinky

3-row and 4-row versions

* refactor default keymaps

- use an enum for layer names
- remove redundant definitions
- qmk cformat pass
- modify pinky/4 via keymap to mirror pinky/4 default functionality

* remove LAYOUT_kc macros

This usage is not endorsed by QMK as it has been found to be confusing to novice users.

* add VIA support to pinky/3

* update config.h files

Removes unnecessary definitions for Backlight, RGB Underglow, Magic config and MIDI.

* update main rules.mk file

Updates the rules.mk file to match the formatting of the current QMK-provided template. Removes sample bootloader comments, feature rules that are no longer included in the template, and updates the in-line comments.

* update and split keyboard readme

Updates the main readme file's formatting, adds instructions to access bootloader mode, and adds more specific readmes for each version.

* add line breaks between rows in the info.json files

* rename layout macros for Community Layout forward compatibility

The layouts of the Pinky3 and Pinky4 aren't currently Community Layouts, but support for them could be added with a rules.mk edit should the layouts be added to QMK.
