Subject: [PATCH] Create radio_ext aidl service declaration

Note: This is copy of the reverted commit
cbc4b64bd1bff8211ef43f8d32856bb342dafa52 (ag/24799507) plus the fix to
the problem that caused the revert which is to mark the radio_ext
service as optional in the compatibility matrix.

Bug: 285459428
Test: manually verified dumpsys and logs that service starts without
errors
