Currently, trusted VM accepts and releases the resources
on RM notifications.
In cases, where TUI fails to submit the first frame on the trusted
vm, display cannot rely on the teardown commit IOCTL to release the
resources back to primary VM.
To handle scenarios where RM notification drops, the VM's should be
able to ACCEPT/RECLAIM resources without relying on the RM.
To address above scenarios, this change moves the resource handling
calls from notification handlers to user prompt. With this change,
trusted VM will ACCEPT the resource only on the first frame commit and
primary VM can RECLAIM the resources back if the TUI use case fails
or any of the RM notifications fail to deliver.

The macros for HH_RM_MEM_NOTIFY_[RECIPIENT/OWNER] have been
updated to be more descriptive, so update the macro
usage in the display files.

Kernel RM IRQ wrapper has changed the prototype of the
notification callback function to support per event
notifications. This uncouples the VM IRQ operations from
their respective notifications.
Adapt the changes in SDE driver by making the notification
handler generic and invoking the notifications calls
explicitly.

Extends atomic check to validate TUI transition request aginst
SDE and non-SDE client states. Triggers HW assignment after
making sure current frame is completely flushed out of HW
pipeline. Initiate the acquire after TUI end after restoring
the software states.

client_pre_release/client_post_acquire hooks in vm_ops allows non-SDE
clients to register for callbacks to be invoked
- before releasing the resources from the current VM so that
the client can updates the respective sw state to indicate
the absence of HW ownership
- before the first frame push after acquiring the HW to update
reset the respective sw state to indicate the presence of
HW ownership and resume operations

Add VM layer files to handle VM specific operations
for primary and secondary VM's. They interact with
Hypervisor RM modules to LEND/ACCEPT/RELEASE/RECLAIM
HW resources. They also handle notifications for each
of the above Hyp RM operations to acquire and update
the SDE software states.
