arm64: itx: Add NEON implementation of itx for 10 bpc
Add an element size specifier to the existing individual transform
functions for 8 bpc, naming them e.g. inv_dct_8h_x8_neon, to clarify
that they operate on input vectors of 8h, and make the symbols
public, to let the 10 bpc case call them from a different object file.
The same convention is used in the new itx16.S, like inv_dct_4s_x8_neon.
Make the existing itx.S compiled regardless of whether 8 bpc support
is enabled. For builds with 8 bpc support disabled, this does include
the unused frontend functions though, but this is hopefully tolerable
to avoid having to split the file into a sharable file for transforms
and a separate one for frontends.
This only implements the 10 bpc case, as that case can use transforms
operating on 16 bit coefficients in the second pass.
Relative speedup vs C for a few functions:
