Per UEFI spec, on CallBack action EFI_BROWSER_ACTION_CHANGING, the return value of ActionRequest will be ignored, but on CallBack action EFI_BROWSER_ACTION_CHANGED, the return value of ActionRequest will be used.
But, EDKII browser still processes the got ActionRequest. And, all HII drivers in EDKII project also returns their expected ActionRequest value on action EFI_BROWSER_ACTION_CHANGING.
Now update the browser to follow the spec, and update all core Hii drivers to keep old working modal.

The Variable PEI and RuntimeDxe drivers were using the attribute 'HeaderLength' of
EFI_FIRMWARE_VOLUME_HEADER without checking if a Firmware Volume Header was existing at
the base address.
In case the Firmware Volume Header does not exist or is corrupted, the attribute 'HeaderLength'
is a non valid value that can lead to a non valid physical address when accessing produces an
access error.

1. Remove memory allocation code in runtime.
2. Exclude NULL terminator in VariableName for serialization data in time-based variable authentication.
3. Add support for enroll PK with WRITE_ACCESS attribute.
4. Initialize SetupMode variable with correct NV attribute.
5. Add support for APPEND_WRITE attribute for non-existing Variable.
6. Clear KEK, DB and DBX as well as PK when user request to clear platform keys.
7. Check duplicated EFI_SIGNATURE_DATA for Variable formatted as EFI_SIGNATURE_LIST when APPEND_WRITE attribute is set.
8. Not change SecureBoot Variable in runtime, only update it in boot time since this Variable indicates firmware operating mode.
9. Save time stamp of PK when PK is set with TIME_BASED_WRITE_ACCESS attribute in setup mode.
10. Update to use PcdMaxVariableSize instead of PcdMaxAppendVariableSize for append operation.
