drm/amdgpu: wire mes_dbgext on gfx11 and gfx12

Browse source

Add the per-IP hardware wiring that drives the mes_dbgext core on gfx11
(mes_v11_0 / gfx_v11_0) and gfx12 (mes_v12_0 / gfx_v12_0): handle
MES_MISC_OP_SETUP_MES_DBGEXT in the misc-op path, unmask the MES debug
interrupt, select the flat (gfx11) or zoned (gfx12) buffer format in
sw_init(), start/stop the feature from hw_init()/hw_fini(), and drain
the log from the EOP interrupt handler while the feature is active.
