Remove generics from DepGraph

[Zoxc]

This removes generics from DepGraph by predefining some properties of dep kinds in rustc_query_system. DEP_KIND_NULL, DEP_KIND_RED, DEP_KIND_SIDE_EFFECT and DEP_KIND_ANON_ZERO_DEPS get their indices assigned in rustc_query_system and the bits needed to encode dep kinds is also hardcoded there. These are checked later in rustc_middle.

read_index, assert_ignored and with_ignore are redefined on DepContext to avoid manual passing of the Deps type.

Overall result: ❌ regressions - please read the text below

Benchmarking this pull request means it may be perf-sensitive – we'll automatically label it not fit for rolling up. You can override this, but we strongly advise not to, due to possible changes in compiler perf.

Next Steps: If you can justify the regressions found in this try perf run, please do so in sufficient writing along with @rustbot label: +perf-regression-triaged. If not, please fix the regressions and do another perf run. If its results are neutral or positive, the label will be automatically removed.
