[PATCH 00/10] Fix PEI Core issue during TemporaryRamMigration

[Jordan Justen <jordan.l.justen@intel.com>]

https://github.com/jljusten/edk2.git temp-ram-support

This series fixes an issue that, while rare, is possible based on the
way the TemporaryRamSupport PPI is defined along with how it is used
by the PEI Core.

Liu Yu reported a boot issue with EmulatorPkg, which I believe was
caused by this issue.

The details of the issue are described in the commit message of the
"MdeModePkg/Core/Pei: Add code path to allow assembly temp-ram
migration" patch.

Along with this, I added a few Temporary RAM patches for EmulatorPkg
and OvmfPkg.
