expects the display dimensions to be set by the caller, and does not

intreadwrite: Use the __unaligned keyword on MSVC for ARM and x86_64

AV_WN64 is meant for unaligned data, but the existing av_alias* unions
(without a definition for the av_alias attribute - we don't have one
for MSVC) indicate to the compiler that they would have sufficient
alignment for normal access, i.e. the compiler is free to assume
8 byte alignment.

On ARM, this makes sure that AV_WN64 (or two consecutive AV_WN32) is
done with two str instructions instead of one strd.

intreadwrite: Add intermediate variables in the byteswise AV_W*() macros

This avoids issues with expanding the argument multiple times,
and makes sure that it is of the right type for the following shifts.

Even if the caller of a macro could be expected not to pass parameters
that have side effects if expanded multiple times, these fallback
codepaths are rarely, if ever, tested, so it is expected that such
issues can arise.

Thefore, for safety, make sure the fallback codepaths only expand
the arguments once.
