Since we're not decoupling just logs, maybe the commit could be renamed to "Decouple ADS and logs from submission"

The Additional Data Struct (ADS) contains objects that are required by
guc post FW load and are not necessarily submission-only (although that's
our current only use-case). If in the future we load GuC with submission
disabled to use some other GuC feature we might still end up requiring
something inside the ADS, so it makes more sense for them to be always
created if GuC is loaded.

To make a concrete example, the pages used by GuC to save state during suspend are allocated as part of the ADS.

Similarly, we still want to access GuC logs even if GuC submission is
disable to debug issues with GuC loading or with wathever we're using GuC for.

v2: Decoupling ads together with logs
v3: Group initialization of GuC objects
