  Log Message:
  -----------
  [CodeGen][NewPM] Port RegAllocEvictionAdvisor analysis to NPM (#117309)

Legacy pass used to provide the advisor, so this extracts that logic
into a provider class used by both analysis passes.

All three (Default, Release, Development) legacy passes
`*AdvisorAnalysis` are basically renamed to `*AdvisorProvider`, so the
actual legacy wrapper passes are `*AdvisorAnalysisLegacy`.

There is only one NPM analysis `RegAllocEvictionAnalysis` that switches
between the three providers in the `::run` method, to be cached by the
NPM.

Also adds `RequireAnalysis<RegAllocEvictionAnalysis>` to the optimized
target reg alloc codegen builder.
