rules.h: Rename ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE
When CONFIG_SEPARATE_VERSTAGE=n, all verstage code gets linked into the
appropriate calling stage (bootblock or romstage). This means that
ENV_VERSTAGE is actually 0, and instead ENV_BOOTBLOCK or ENV_ROMSTAGE
are 1. This keeps tripping up people who are just trying to write a
simple "are we in verstage (i.e. wherever the vboot init logic runs)"
check, e.g. for TPM init functions which may run in "verstage" or
ramstage depending on whether vboot is enabled. Those checks will not
work as intended for CONFIG_SEPARATE_VERSTAGE=n.
This patch renames ENV_VERSTAGE to ENV_SEPARATE_VERSTAGE to try to
clarify that this macro can really only be used to check whether code is
running in a *separate* verstage, and clue people in that they may need
to cover the linked-in verstage case as well.
