Subject: [PATCH] refactor(compiler-cli): remove redundant
 `potentialSourceMapUrl` property (#42000)

Now that there is no need to work around the source-map bug in TypeScript
(https://github.com/Microsoft/TypeScript/issues/29300) we can just use
`resolvedTemplateUrl` for the source-map URL, rather than having a separate
property.

PR Close #42000
