EmbeddedPkg: PrePi.h: Drop Duplicate HOB Defintions
PrePi.h has some duplicate HOB definitions from HobLib.h.
Instead of redefining them, use HobLib.h.

EmbeddedPkg: PrePiLib: Skip Extracting if FV3 HOB Found
PrePiLib only searches for the existence of an FV2 HOB to
determine if an FV has already been extracted. However,
FV2 HOBs have been superceded by FV3 HOBs for describing extracted
FVs.
This commit updates PrePiLib to check for the existence of either
an FV2 or FV3 HOB for this FV and skips extracting if either is
found.

EmbeddedPkg: PrePiLib: Zero Volume Info Buffer Before Writing
FfsGetVolumeInfo() in PrePiLib does not zero the VolumeInfo
buffer before writing to it. However, it has some fields that
are expected to be zero if certain conditions are not met.
For example, the FvName is expected to be all 0's if the
extended header is not present in the FV. Currently,
the FvName field will point to garbage if the caller does
not zero the buffer first.
Flip the expectation and have FfsGetVolumeInfo() zero the
buffer before it writes to it.

EmbeddedPkg, OvmfPkg: PrePiLib: Use Correct FvName in FV2 HOB Production
PrePiLib is incorrectly producing FV2 HOBs. The FvName field of
the FV2 HOB is intended to be the parent FV's name. This way the
HOB consumer phase can identify when an FV has already been
extracted: if the file name of the extracted FV and the parent
FV name match in the FV2 HOB.
With the incorrect FvName, DXE will re-extract the already
extracted FV, which can be a large performance hit (some platforms
we have seen ~1 second).
This requires an update to FfsProcessFvFile to pass the parent
FV handle through so the FV2 HOB can be correctly produced.
OvmfPkg consumers are also updated.

EmbeddedPkg, OvmfPkg: Produce FV3 HOBs for Extracted FVs
EmbeddedPkg's PrePiLib and OvmfPkg's PeilessStartupLib (which
uses PrePiLib) only produce FV2 HOBs for extracted FVs. However,
FV3 HOBs have superceded FV2 HOBs for describing extracted FVs.
This commit updates both of these libs to also produce FV3 HOBs,
following PEI's pattern of producing an FV, FV2, and FV3 HOB for
each extracted FV.
Eventually, only FV3 HOBs will be produced, so this paves the way
for that.
