Replace most Bzlmod events with a Skyframe graph lookup

Retaining `Postable`s across the graph increases the memory usage of every dependent Skyframe node.

`ModuleExtensionResolutionEvent` is replaced with a lookup of the "done" Skyframe nodes for extension evaluation in `BazelLockFileModule#afterCommand`.

`RootModuleFileFixupEvent` is replaced with direct storage in `SingleExtensionEvalValue`. The validation of repos imported from an extension is moved into a separate `SkyFunction`. This simplifies `bazel mod tidy`, which no longer needs to swallow certain exceptions, and allows cache hits when only the (invalid) imports of an extension are modified even without the lockfile.

The `BazelModuleResolutionEvent` is kept for now, but will become obsolete with the new lockfile format.

Work towards #20369

Closes #22058.
