Pete Bacon Darwin 348ff0c8ea perf(ngcc): use binary search when flattening mappings (#36027)
The `@angular/core` package has a large number of source files
and mappings which exposed performance issues in the new source-map
flattening algorithm.

This change uses a binary search (rather than linear) when finding
matching mappings to merge. Initial measurements indicate that this
reduces processing time for `@angular/core` by about 50%.
