Struct packing is only necessary for data structures whose in-memory
representation is covered by the PI or UEFI specs, and may deviate
from the ordinary C rules for alignment.
So in case of FileExplorerLib, this applies to the device path struct
only, and other structures used to carry program data should not be
packed, or we may end up with alignment faults on architectures such
as ARM, which don't permit load/store double or multiple instructions
to access memory locations that are not 32-bit aligned.
E.g., the following call in FileExplorerLibConstructor()
InitializeListHead (&gFileExplorerPrivate.FsOptionMenu->Head);
which is emitted as follows for 32-bit ARM/Thumb2 by Clang-5.0
3de0: b510 push {r4, lr}
3de2: 4604 mov r4, r0
...
3de8: e9c4 4400 strd r4, r4, [r4]
3dec: bd10 pop {r4, pc}
will perform a double-word store on the first argument, passed in
register r0, assuming that the pointer type of the argument is
enough to guarantee that the value is suitably aligned.

When user select and enter a directory, File Explorer will update the
form based on the new folders and files in the directory. But when
creating question opcodes, the question id is same with previous one
and this will cause browser to show the highlight menu incorrectly.
