The application usage used by report 1 is `HID_USAGE_GD_KEYBOARD`. Moreover, the `keys` usage page (0x07) that primarily feeds into this report is predominantly keyboard codes. The rest of the system should align with this naming convention.
* Add back in profiles, not using Zephyr
BT identity infrastructure.
* Restore additional `&bt` commands for profile
operations.
* Fix for split pairing and subscriptions, since
Zephyr persists subscriptions across connects.
* Remove keymap from peripheral builds, reduces
firmware size, and avoids unneeded attempts
to send HID data.
* Move all headers to `include/zmk` directory.
* Update includes to reference them properly.
* Add `keymap.c` file from keymap, if found.
* Toplevel CONFIG_ZMK_BLE aggregate config setting.
