x86/tx_float: add 15xN PFA FFT AVX SIMD
~4x faster than the C version.
The shuffles in the 15pt dim1 are seriously expensive. Not happy with it,
but I'm contempt.

Can be easily converted to pure AVX by removing all vpermpd/vpermps
instructions.

15cfb4eee3 checkasm: Use the correct AVTXContext in av_tx tests
Keep a reference to the correct associated context of the reference
function and use that context when calling the reference function.

checkasm: add av_tx FFT SIMD testing code
This sadly required making changes to the code itself,
due to the same context needing to be reused for both versions.
The lookup table had to be duplicated for both versions.
