It's not needed nor used by anything anymore, lavu/tx is faster,
and better in every way. RIP.

Thanks to Martin Storsjö <martin@martin.st> for fixing and testing the
arm32 and aarch64 changes.

Negligible speed difference for avx2 on Zen 2 (Ryzen 5700X) and
Broadwell (Xeon E5-2620 v4):
1690±4.3 decicycles vs. 1693±78.4
1439±31.1 decicycles vs 1429±16.7
Moderate speedup with avx512 on Skylake-X (Xeon D-2123IT):
1.22x faster (793±0.8 vs. 649±5.5 decicycles) compared with avx2
Better speedup with avx512icl on Ice Lake (Xeon Silver 4316):
1.77x faster (784±1.8 vs. 442±11.6 decicycles) compared with avx2

It is only used by gmc/gmc1 which is only used by the MPEG-4
decoder, so move it to Mpeg4DecContext and rename it
to Mpeg4VideoDSP. Also compile it iff the MPEG-4 decoder is compiled.

Currently, SVQ1EncContext is defined in a header that is also
included by the arch-specific code that initializes the one
and only dsp function that this encoder uses directly.
But the arch-specific functions to set this dsp function
do not need anything from SVQ1EncContext. This commit therefore
adds a small SVQ1EncDSPContext whose only member is said
function pointer and renames svq1enc.h to svq1encdsp.h
to avoid exposing unnecessary internals to these init
functions (and the whole mpegvideo with it).

Pointers to void can be converted to any pointer to incomplete or
object type and back; but they are nevertheless not completely generic
pointers: There is no provision in the C standard that guarantees their
convertibility with function pointers. C90 lacks a generic function
pointer, C99 made every function pointer a generic function pointer and
still disallows the convertibility with void *. Both GCC as well as
Clang warn about this when using -pedantic.
Therefore use unions to avoid these conversions.

Old one was written with the assumption only even inputs would be given.
This very messy replacement supports even and odd inputs, and supports
AVX2 for extra speed. The buffers given are usually quite big (4k samples),
so the speedup is worth it.
The new SSE version is still faster than the old inline asm version by 33%.
Also checkasm is provided to make sure this monstrosity works.
This fixes some FATE tests.

Inside a function, the second ';' in ";;" is just a null statement,
but it is actually illegal outside of functions. Compilers
nevertheless accept it without warning, except when in -pedantic
mode when e.g. Clang emits a -Wextra-semi warning. Therefore
remove the unnecessary ';'.

The height is hardcoded in some of the me_cmp functions, but not
in all of them. But in the case of all other functions, it's hardcoded
in the same place in SIMD functions as in the C reference functions,
while this one function differs from the behaviour of the C code.
(Before 542765ce3eccbca587d54262a512cbdb1407230d, there were a
couple other sad8_*_mmx functions with similar hardcoded height.)

Forgotten in 4011a76494a5ff6844312813bc753aae8e54c2f0.
The reason for this is that these functtions are marked
as av_always_inline and GCC does not emit warnings
if such functions are unused, so this went unnoticed.
Yet Clang does, so this commit removes them.
