[PATCH v4 0/2] Enable GuC opt-in features

[Daniele Ceraolo Spurio]

The GuC supports a H2G to opt-in to extra features on a per-VF basis.
We're interested in 2 of those features:

1 - Extended CAT error info (extra debug info)
2 - Dynamic ICS (optimization)

More details on what those do in the respective patches.

This series adds code to conditionally enable those features in both
native/PF and VF. Note however that for the VF enablement to actually
work we need another series to correnctly set the GuC compatibility
version ([1]), but these patches can be merged in parallel as there is no
direct dependency in code.

v2: rework common KVL emission code.
v3: switch to guc_buf_cache instead of using a dedicated allocation.
v4: limit dynamic ICS to single engine cases.
