avcodec/liblc3enc: support packed float (AV_SAMPLE_FMT_FLT) input.HEADmaster

Previously, the LC3 encoder only accepted planar float (AV_SAMPLE_FMT_FLTP).
This change extends support to packed float (AV_SAMPLE_FMT_FLT) by properly
handling channel layout and sample stride.

The pcm data pointer and stride are now calculated based on the sample
format: for planar, use frame->data[ch]; for packed, use frame->data[0]
with channel offset. The stride is set to 1 for planar and number of
channels for packed layout.

This enables encoding from common packed audio sources without requiring
a prior planar conversion, improving usability and efficiency.
