fix(language-service): Use ts.CompletionEntry for completions (angula…

…r#32375)

This is a prerequisite to fix a bug in template completions whereby
completion of the string `ti` for the variable `title` results in
`tititle`.

This is because the position where the completion is requested is used
to insert the completion text. This is incorrect. Instead, a
`replacementSpan` should be used to indicate the span of text that needs
to be replaced. Angular's own `Completion` interface is insufficient to
hold this information. Instead, we should just use ts.CompletionEntry.

Also added string enum for `CompletionKind`, which is similar to
ts.ScriptElementKind but contains more info about HTML entities.
