This commit consolidates the options that can modify the parsing of text (e.g. HTML, Angular templates, CSS, i18n) into an AST for further processing into a single `options` hash. This makes the code cleaner and more readable, but also enables us to support further options to parsing without triggering wide ranging changes to code that should not be affected by these new options. Specifically, it will let us pass information about the placement of a template that is being parsed in its containing file, which is essential for accurate SourceMap processing. PR Close #28055
