OvmfFindLoadOption behaves like EfiBootManagerFindLoadOption, it searches for
an entry in the array: an entry is found if the two paths are equal.
This removes possible duplicates in the boot entries: two entries with
the same path and different attributes are not detected as equal by
EfiBootManagerFindLoadOption.
In this case, the old entry is deleted and replaced by the new one.

Many function present in PlatformBootManagerLib and
PlatformBootManagerLibLight have the same implementation. The idea of
this new Library is to collect them to enable code reuse.
