fix(compiler-cli): compute source-mappings for localized strings (#38747)

Browse Source 
Previously, localized strings had very limited or incorrect source-mapping
information available.

Now the i18n AST nodes and related output AST nodes include source-span
information about message-parts and placeholders - including closing tag
placeholders.

This information is then used when generating the final localized string
ASTs to ensure that the correct source-mapping is rendered.

See #38588 (comment)
