clang exposes this intrinsic even in 32-bit mode, if targeting >= armv8,
whereas gcc does not, see:

Compilers sometimes replace vmlaq*() with fmul+fadd instead of fmla.
Trying to use vfmaq*() instead when possible.

Still missing some intrinsics

Should be able to handle all previous GRU variants and more.

Depending on what defines are set there is collisions with the ones
in Opus. To avoid these errors we rename the exp functions and
macros.

first attempt of C implementation of fec encoder (not tested yet due to NEON/DOT_PROD not being separable)

The 4* is now stored in the table to avoid computing it in the loop

Saves on the MDense/softmax computation since we only need to compute
8 values instead of 256.

Otherwise it was splitting the mla into a mul and an add
