avcodec/aac/aacdec_(fixed|float): Set AACDecDSP, AACDecProc directly
...
This is more in line with how we initialize DSP functions
and avoids tables of function pointers as well as relocations
for these.

avcodec/aac/aacdec: Move init functions to aacdec_fixed/float
...
This allows to merge it with AACDecDSP.init and remove the latter
(it is called only once anyway); it also allows to make
the fixed/float AACDecDSP and AACDecProc implementations internal
to aacdec_fixed/float.c (which also fixes a violation of our
naming conventions). And it some linker errors when either decoder
is disabled.

aacdec: remove AAC-specific MIPS optimizations
...
The code was written in 2012, but seems to have been broken
for just as long. Compilation is broken on every MIPS/MIPS64
system with an FPU (which the code depends on).

Unfortunately, although it's a purely decode function, it does
