Remap syntax contexts and expansion ids for det. metadata encoding

[aerooneqq]

#163495 which parallelizes AST -> HIR lowering breaks det. encoding of syntax contexts and expansions, however this PR with #162809 should fix the problem.

Now draft for perf and CI (dont look at the code). Remapping of those entities can cost us much, because unlike def ids there may be many expansions and contexts after we committed end of determinism.

Finished benchmarking commit (a7c6732): comparison URL.

Overall result: ❌✅ regressions and improvements - please read:

Benchmarking means the PR may be perf-sensitive. It's automatically marked not fit for rolling up. Overriding is possible but disadvised: it risks changing compiler perf.

Next, please: If you can, justify the regressions found in this try perf run in writing along with @rustbot label: +perf-regression-triaged. If not, fix the regressions and do another perf run. Neutral or positive results will clear the label automatically.
