mb/google/brya: Add new skolas baseboard

This commit adds the skolas baseboard, which is basically the brya
baseboard, but using an Intel Raptor Lake-P SoC instead of an Alder
Lake SoC.

This commit also adds the skolas baseboard variant skolas4es.

Since this baseboard is identical to the brya baseboard with the
exception of the SoC used, the new baseboard and the new baseboard's
first variant will be a copy of the current brya baseboard and brya0
variant.

For now, the skolas baseboard and skolas4es variant will continue to
use ADL-P.  This allows for two benefits:
  1. software to be proven out on existing hardware prior to RPL SoC
	support landing, and
  2. allows us not to have to wait for RPL SoC changes prior to getting
	the mainboard changes in place

Once the RPL SoC code has merged, I will update the skolas baseboard and
skolas4es variant to use RPL instead of ADL.
