keyboard_scan: Add refresh and power button boot key options
Make Esc+Refresh+Power on Grunt enter Recovery Mode.
If Power is released fast:
[0.045303 KB init state: -- 02 08 -- -- -- -- -- -- -- -- -- --]
Add CONFIG_KEYBOARD_IGNORE_REFRESH_BOOT_KEY to handle this case.
If Power is held longer:
[0.045448 KB init state: 08 0a 08 08 08 -- 08 -- 08 08 -- 08 08]
Add CONFIG_KEYBOARD_PWRBTN_ASSERTS_KSI3 to handle this case.
BUG=b:79758966
BRANCH=none
TEST=Esc+Refresh+Power gives recovery screen on Grunt
