Arm ps2 mouse interrupt (#6490)
* ps2_mouse on ARM: an interrupt-version of the ps2-mouse code ported to ARM/chibios

* ps2_mouse on ARM: link EXT callback-channel selection to the user defined PS2_LINE_CLOCK

* ps2_mouse on ARM: replace DELAY_X defines with hardware-agnostic wait_X

* ps2_mouse on ARM: replace chibios-specific defines for the pins/lines with defines from quantum/config_common.h

and drop the '_LINE' component from teh define name

* ps2_mouse on ARM: expose the software-intterupt port as a user editable define

* Update docs/feature_ps2_mouse.md

Co-Authored-By: Hugo van Kemenade <hugovk@users.noreply.github.com>

* Update feature_ps2_mouse.md

* use a define to deduce the PS_DATA_PORT instead

* reduce all-zero extcfg to oneliner

* ps2_mouse: use generic wait instead of avr-delay

* Update docs/feature_ps2_mouse.md

* ps2_mouse: changes for new chibios version

(17.6.0 -> 19.1.0)
replacing the legacy externa-interrupt driver with pal-callbacks

* ps2_mouse: use PLATFORM_KEY

Co-Authored-By: Joel Challis <git@zvecr.com>

* ps2_mouse: clang-format corrections

* ps2_mouse: add systemlocks

using the chibios equivalent to AVRs cli: chSys[Unl|L]ock
