roms: lift "edk2-funcs.sh" from "tests/uefi-test-tools/build.sh"

Browse source 
Extract the dense logic for architecture and toolchain massaging from
"tests/uefi-test-tools/build.sh", to a set of small functions. We'll reuse
these functions for building full platform firmware images.

# Expose cross_prefix (which is possibly empty) to the edk2 tools. While at it,

# - For ARM and AARCH64, edk2 only offers the GCC5 toolchain tag, which covers
# the gcc-5+ releases.
# - For IA32 and X64, edk2 offers the GCC44 through GCC49 toolchain tags, in
# addition to GCC5. Unfortunately, the mapping between the toolchain tags and
# the actual gcc releases isn't entirely trivial. Run "git-blame" on
# "OvmfPkg/build.sh" in edk2 for more information.
# And, because the above is too simple, we have to assign cross_prefix to an
# edk2 build variable that is specific to both the toolchain tag and the target
