Sagar Ghuge ada713b32f anv: Fix Wa_14021821874, Wa_14018813551, Wa_14026600921
WA states that we need to allocate maximum number of stackIDs per DSS
from RT_DISPATCH_GLOBALS to 2048.

We can still throttle/control the CFE_STATE::StackID to be in range
specified by the field.

This does impact performance having CFE_STATE::stackIDs capped to 2K
by default. More the outstanding ray queries, larger the working set and
have more impact on cache hit rate.

This affect performance on Xe2+ onwards:
* Boundary Benchmark:            36.2%
* Solar Bay extreme:             9.8%
* Hitman world of assassination: 3.9%

Fixes: c1a44e8d43 ("anv: force StackIDControl value for Wa_14021821874")
