feat(rme) : introduce new build flag for RME stack
* Introduce new build flag ENABLE_REALM_PAYLOAD_TESTS to build
Realm Payload Tests and pack realm image to tftf.bin.
* Also enable PAuth for TFTF and Realm Payload by default
for RME stack.
* This commit deprecates the use of `pack_realm` build target.
* The patch also modifies the user guide instructions to build
and pack realm payload tests.
NOTE: The `pack_realm` build target, even though deprecated,
is still available for compatibility reasons. It will be
removed in a future commit.
