Oliver Smith-Denny d417f3ec34 MdeModulePkg: Dxe: Skip FV Extraction When FV3 HOB Found Currently, the DXE dispatcher will skip extracting an FV file when an FV2 HOB is found for it, as that indicates pre-DXE extracted it. However, the dispatcher does not check for FV3 HOBs, which also can describe extracted FVs. That can result in extracting the same FV in DXE that is already extracted, which can be a large performance hit. This updates the DXE dispatcher to check for the existence of either an FV2 or FV3 HOB for this FV and skip extracting if either is found.

Oliver Smith-Denny d417f3ec34 MdeModulePkg: Dxe: Skip FV Extraction When FV3 HOB Found

Currently, the DXE dispatcher will skip extracting an FV file
when an FV2 HOB is found for it, as that indicates pre-DXE
extracted it.

However, the dispatcher does not check for FV3 HOBs, which also
can describe extracted FVs. That can result in extracting the
same FV in DXE that is already extracted, which can be a large
performance hit.

This updates the DXE dispatcher to check for the existence of
either an FV2 or FV3 HOB for this FV and skip extracting if either
is found.
