When update contents in HiiDatabase, like:
1. Add/update/remove package list
2. Add/update string
3. Add/update image
We should make these operations atomic to prevent the
potential issue that the one update operation with
higher TPL may interrupt another.
This commit is to make the HiiDatabase update behaviors
atomic by adding EfiAcquireLock/EfiReleaseLock function.
