Add definition for ENV_ROMSTAGE_OR_BEFORE to <rules.h>

Browse Source 
ENV_ROMSTAGE_OR_BEFORE is a direct replacement for testing
defined(__PRE_RAM__) as a true statement instead of with the
help of the preprocessor.

Note that for x86, due to existence of ENV_POSTCAR and ENV_SMM,
ENV_ROMSTAGE_OR_BEFORE and ENV_RAMSTAGE are not the inverse of
each other.
