sm6375-common: Make fastrpc_shell_3 publicly available

Browse Source 
* 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.

[ghostrider-reborn]:
Allow adsp/cdsprpcd and neuralnetworks HAL to access fastrpc_shell_3

[kras edit:
 1. rename some contexts as per qva/kona
 2. extend to allow camera HAL and VPP service to access it as well]
