Merge branch 'compiler_types-add-endianness-dependent-__counted_by_-le-be'

Alexander Lobakin says:

====================
compiler_types: add Endianness-dependent __counted_by_{le,be}

Some structures contain flexible arrays at the end and the counter for
them, but the counter has explicit Endianness and thus __counted_by()
can't be used directly.

To increase test coverage for potential problems without breaking
anything, introduce __counted_by_{le,be} defined depending on platform's
Endianness to either __counted_by() when applicable or noop otherwise.
The first user will be virtchnl2.h from idpf just as example with 9 flex
structures having Little Endian counters.

Maybe it would be a good idea to introduce such attributes on compiler
level if possible, but for now let's stop on what we have.
