1. Remove ASSERT when failed to Get/Set "AttemptOrder" and "ClientId" variable.
   Removes RT attribute for "AttemptOrder" variable.
2. Fix the return status when physical presence variable and MemoryOverwriteRequestControl variable are corrupt.
3. Remove ASSERT check for SetVariable in FirmwarePerformanceDataTableDxe.
4. Add comments to describe PlatformDriOverrideDxe is used for test purpose. 
5. Remove unnecessary dependency in variable driver.
6. Remove the RT attribute for the MemoryTypeInformation variable because it’s not necessary.
7. Add comments for PcdHideTpmSupport.
8. Remove ASSERT when SetVariable for ConOutDev/ConInDev/ErrOutDev variables failed.
