Accessing to software SRAM region is not allowed when
software SRAM is pass-thru to prelaunch RTVM.
This patch removes software SRAM region from service VM
EPT if it is enabled for prelaunch RTVM.

Currently, we hardcode the GPA base of Software SRAM
to an address that is derived from TGL platform,
as this GPA is identical with HPA for Pre-launch VM,
This hardcoded address may not work on other platforms
if the HPA bases of Software SRAM are different.
Now, Offline tool configures above GPA based on the
detection of Software SRAM on specific platform.
This patch removes the hardcoding GPA of Software SRAM,
and also renames MACRO 'SOFTWARE_SRAM_BASE_GPA' to
'PRE_RTVM_SW_SRAM_BASE_GPA' to avoid confusing, as it
is for Prelaunch VM only.

Physical address to SW SRAM region maybe different
on different platforms, this hardcoded address may
result in address mismatch for SW SRAM operations.
This patch removes above hardcoded address and uses
the physical address parsed from native RTCT.

'ptcm' and 'ptct' are legacy name according
to the latest TCC spec, hence rename below files
to avoid confusing:
ptcm.c -> rtcm.c
ptcm.h -> rtcm.h
ptct.h -> rtct.h
