Karthikeyan Ramasubramanian dc4989351f util/amdfwtool: Consolidate entry line regex pattern 
There are 2 regex patterns defined to process the lines from *fw.cfg:
1) for lines with mandatory entries
2) for lines with mandatory + optional entries

Consolidate the regex pattern. Add enums for matching regex caller
groups so that the human readable group IDs can be used instead of magic
numbers.

BUG=None
TEST=Build Skyrim BIOS which only have mandatory entries. Build Guybrush
BIOS image which have both mandatory and optional entries. Confirm that
the amdfw.rom built before and after this change have matching SHA in
both Skyrim and Guybrush images. This ensures that the optional level
entries in Guybrush are handled as expected. Boot to OS in Skyrim.
