[keyboard] bastardkb: restructure folder hierarchy (#16778)

* bastardkb: restructure folder hierarchy ahead of supporting other adapters/mcus

Upcoming support for the following (adapter, mcu) pairs will be
submitted in follow-up PRs:

- `v2/elitec`
- `v2/stemcell`
- `blackpill`

This PR contains the following changes:

- Move previous implementation to an inner `v1/elitec` folder
- Move keyboard USB IDs and strings to data driven
- Update headers to update maintainers list
- Run `qmk format-c`

* bastardkb/charybdis: remove broken acceleration implementation

* bastardkb/charybdis: fix debug output

* bastardkb: add support for BastardKb the `v2/elitec` (adapter, mcu) pair

* bastardkb: add Blackpill support

* bastardkb/charybdis/3x5: add `bstiq` keymap

* bastardkb/charybdis: add fake LEDs to the configuration

For the Charybdis 3x5 (respectively 4x6), the LED config now simulates
36 (respectively 58) LEDs instead of the actual 35 (respectively 56) to
prevent confusion when testing LEDs during assembly when handedness is
not set correctly.  Those fake LEDs are bound to the physical
bottom-left corner.

* bastardkbk/charybdis/readme.md: update build commands

Merge pull request #5 from Nathancooke7/update_charybdis_readme_v2_shield.

* bastardkb/charybdis: fix Via keymap with blackpill

* bastardkb/charybdis: remove unnecessary files

* bastardkb/charybdis: remove obsolete code

* bastardkb/charybdis/3x6: add Via keymap

* bastardkb: add support for Splinky (RP2040) board

* bastardkb: initial configuration for the Splinky (SPI not working yet)

* bastardkb/charybdis/3x5/v2/splinky: tentative change to enable trackball

* bastardkb/charybdis/3x5/v2/splinky: fix SCK, MISO, MOSI pins

* bastardkb/charybdis/3x5/v2/splinky: fix SCK, MISO, MOSI pins

* bastardkb/charybdis/4x6/v2/splinky: add SPI configuration and enable trackball

* bastardkb/charybdis/3x6: add splinky config

* bastardkb/*/v2/splinky: update drivers to `vendor`

* bastardkb/dilemma: add new board

* bastardkb/charybdis: fix infinite loop in `layer_state_set_user(…)` in the `via` keymaps

* bastardkb/dilemma: add `bstiq` keymap

* bastardkb: specify blackpill boards

* bastardkb/charybdis: fix blackpill-specific define syntax

* bastardkb: remove `NO_ACTION_MACRO` and `NO_ACTION_FUNCTION` which are no longer valid options

* bastardkb: fix `QK_BOOT` keycodes

* bastardkb/dilemma: fix mouse direction on X axis

* bastardkb/charybdis/3x6: adjust CS

* bastardkb/dilemma: adjust trackpad configuration

* charybdis: fix `PWM33XX_CS_PIN` defines

This is a follow-up of https://github.com/qmk/qmk_firmware/pull/17613.

* bastardkb: remove Vial mentions from `bstiq` keymaps

* Cleanup unnecessary comments
