msm: camera: memmgr: Add provision for heap selection

Currently, userland can only choose whether to allocate memory as
cached/uncached if it's a protected buffer, ubwc_p buffer, etc.
This change provides some more granularity in terms of heap selection.
One could now force an allocation from the system heap or
try a dedicated heap. The change also provides heap capability info
to userland as part of the query caps call.
