bluetooth: ldac: Use format as FLOAT32LE

Merged Sanchayan Maity requested to merge SanchayanMaity/pulseaudio:ldac-use-f32 into master

LDAC encoder already supports S16, S24, S32 and F32LE. Using FLOAT32LE for the sample format would avoid the additional call for conversion to pa_sconv_s32le_from_float32ne. perf tool shows this as being the function called frequently after encode. So, just avoid this by using sample format as F32LE.

For reference, also see discussion here.

NOTE: Dependent on !484 (merged) and needs to rebased once that is merged.
