refactor(makefile): remove BL prefixes in build macros

The current Makefile assumes all TF-A binaries
have BL prefixes (BL1, BL2, etc). Now that we
have other binary names with FEAT_RME feature, remove
this assumption. With this change, we need to pass
the full name of a binary when using build macros.
