* Workaround for ensuring macOS pairing happens early enough,
for their stack, we require encryption for the hids report map and
report ref characteristics as well, to trigger pairing ealier in the
connection process for macOS.
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.
