MinPlatform/build_bios.py: Support performance enabled build

build_bios.py supports caller to pass in "--performance" flag but the
script implemnetation just ignores this flag.

The patch adds the missing logic to invoke build.py with
"--pcd gMinPlatformPkgTokenSpaceGuid.PcdPerformanceEnable=True"
when "--performance" is supplied.
