…gnostics When reporting type-checking diagnostics in external templates we create a `ts.SourceFile` of the template text, as this is needed to report Angular template diagnostics using TypeScript's diagnostics infrastructure. Each reported diagnostic would create its own `ts.SourceFile`, resulting in repeatedly parsing of the template text and potentially high memory usage if the template is large and there are many diagnostics reported. This commit caches the parsed template in the template mapping, such that all reported diagnostics get to reuse the same `ts.SourceFile`. Closes angular#47470
