Add new UABI and implementation of PERFCNTR_CONFIG ioctl. A bit more work is required to configure the pwrup_reglist for the GMU to restore SELect regs on exit of IFPC, before we can stop disabling IFPC while global counter collection. This will follow in a later commit, but will be transparent to userspace.

Add VIRTGPU_PARAM_BLOB_ALIGNMENT as a param that can be read with VIRTGPU_GETPARAM by userspace applications running in the guest to obtain the host's page size and find out the right alignment to be used in shared memory allocations.

If userspace never maps GEM object, then BO wastes hostmem space because VirtIO-GPU driver maps VRAM BO at the BO's creating time. Make mappings on-demand by adding new RESOURCE_CREATE_BLOB IOCTL/UAPI hinting flag telling that host mapping should be deferred until first mapping is made when the flag is set by userspace.

Expose the command doorbell register to userspace on a per-hardware context basis, enabling applications to notify the firmware of pending commands via doorbell writes. Introduce DRM_IOCTL_AMDXDNA_WAIT_CMD to allow userspace to wait for completion of individual commands.
