cmd/go/internal/modload: cache parsed go.mod files globally

Previously they were cached per mvsReqs instance. However, the
contents of the go.mod file of a given dependency version can only
vary if the 'replace' directives that apply to that version have
changed, and the only time we change 'replace' directives is in 'go
mod edit' (which does not care about the build list or MVS).

This not only simplifies the mvsReqs implementation, but also makes
more of the underlying logic independent of mvsReqs.

For #36460
