avcodec/aacdec_fixed: Move fixed-point sinewin tables to its only user
The fixed-point AAC decoder is the only user of the fixed-point sinewin tables from sinewin; and it only uses a few of them (about 10% when counting by size). This means that guarding initializing these tables by an AVOnce (as done in 3719122065863f701026632f610175980d42b05a) is unnecessary for them. Furthermore the array of pointers to the individual arrays is also unneeded. Therefore this commit moves these tables directly into aacdec_fixed.c; this is done by ridding the original sinewin.h and sinewin_tablegen.h headers completely of any fixed-point code at the cost of a bit of duplicated code (the alternative is an ugly ifdef-mess). This saves about 58KB from the binary when using hardcoded tables (as these tables are hardcoded in this scenario); when not using hardcoded tables, most of these savings only affect the .bss segment, but the rest (< 1KB) contains relocations (i.e. savings in .data.rel.ro).
