Fully remove floating point code from libmusepack. Introduce two small const arrays for precalculated scalefactors, correct the integer type of scalefactors to unsigned, migrate some metadata calculations to fixed point. No impact to decoder output.

Set alignment for major data arrays in the mpc codec. This avoids performance regressions on S5L870x CPUs when changing code and allows further improvements.
