cue/build,cue/load: remove deprecated fields

build.Instance's ImportComment and AllTags were deprecated in v0.10.0
as they were remnants of the port from Go's go/build package.
Given that they were never used, deprecating for one release cycle
seems enough, so they can be removed entirely for v0.11.

load.Config's StdRoot was deprecated in March 2024, for v0.9.0,
and the last use of it was removed in August 2019.
Just like with cue/build, now is time to remove it for v0.11.
