[AMDGPU] Add support for GFX11 LDSDIR hazards
Detect LDS direct WAR/WAW hazards and compute values for
wait_vdst (va_vdst) parameter. Where appropriate this
raises wait_vdst from the default 0 to allow concurrent
issue of LDS direct with VALU execution.
Also detect LDS direct versus VMEM source VGPR hazards
and insert vm_vsrc=0 waits using s_waitcnt_depctr.
