cameraserver: Add support for session specific hal buffer manager switches

With ICameraDeviceSession V3, it is possible for HALs to toggle HAL
buffer manager on and off depending on the session configuration.
Add support to cameraserver to switch HAL buffer manager behavior
for the session - depending on what the HAL decides.

Test: Use GCA on device not advertising session hal buffer manager
