drm/amdgpu: Add GFX 9.5.0 support for per-queue/pipe reset

Browse Source 
This patch enables per-queue and per-pipe reset functionality for
GFX IP v9.5.0 when using MEC firmware version 21 (0x15) or later.

This change:
1. Refactors the pipe reset support check in gfx_v9_4_3_pipe_reset_support()
   to use the compute_supported_reset flags instead of hardcoding
   version checks.
2. Adds support for GFX9.5.0 (IP 9.5.0) with MEC firmware version >= 21
   to enable per-queue and per-pipe reset capabilities.

v2: Replaced mec version check with !!(adev->gfx.compute_supported_reset & AMDGPU_RESET_TYPE_PER_PIPE) (Lijo)
