refactor(compiler-cli): add `TemplateId` to template diagnostics (#38105)

Previously, a stable template id was implemented for each component in a
file. This commit adds this id to each `TemplateDiagnostic` generated from
the template type-checker, so it can potentially be used for filtration.

PR Close #38105
