Martin Storsjö fb65ecbc9b avutil: Fix linking x86 asm constants with Clang in MSVC mode ...

This fixes building with Clang in MSVC mode, for x86, which was
broken in 6e49b86996 (in Nov 2024);
previously it failed with undefined symbols for the constants
defined with DECLARE_ASM_CONST, accessed via inline assembly.

Before 57861911a3, there was an
    #elif defined(__GNUC__) || defined(__clang__)
case before the
    #elif defined(_MSC_VER)
case for defining DECLARE_ASM_CONST, which included av_used.
(This case included the explicit "defined(__clang__)" since
f637046d3134a331e4b5a7243ac3dfb92735b8a5.)

After 57861911a3, it used the
generic definition of DECLARE_ASM_CONST that also included
av_used - which also worked for Clang in MSVC mode. But after
6e49b86996, Clang in MSVC mode
ended up using the MSVC specific variant which lacked the
av_used declaration, causing linker errors due to undefined
symbols.
