sdm660-common: Make fastrpc_shell_3 publicly available
* Used by GCAM for DSP-accelerated HDR processing
* Arguably we should label /vendor/dsp/cdsp/fastrpc_shell_3 to
same_process_hal_file like Pixels, but the partition is prebuilt thus
we're unable to relabel it.
* Copy the file to writable tmpfs, setup attributes and bind mount back
to workaround the limitation.
