Refactor `bastardkb/charybdis/3x5` (#25488)

* Refactor bastardkb/charybdis/3x5

- Migrate various configuration to data-driven
- Use short SPDX license headers
- Remove configuration that trends towards user-specific (CRC Table)
- Migrate common configuration upwards
- Migrate keymap to JSON
- Remove likely unneeded v1 revision per #23638
- Remove revisions splinky_2, splinky_3, and stemcell where a converter
  should be used
- Rename v2/elitec -> elitec. Specifically named elitec, as this board
  requires pin compatibility with an Elite-C (bottom 5 pins)
