Add a firmware module to load, parse, and map the MCU firmware sections
into shared GEM memory at the required virtual addresses accessible by the
GPU.

Create a firmware instance during probe and store it inside the
TyrDrmRegistrationData to keep it alive after probe. Use the firmware
instance to boot the MCU.

Remove the dead-code annotations from the MMU, VM, slot manager, and
kernel BO code now that these paths are used by the firmware module.

Update Kconfig to add the RUST_FW_LOADER_ABSTRACTIONS dependency
required by this module.
