refactor(compiler): allow parsing templates with custom leadingTriviaChars (#31136) 

Move the definition leadingTriviaChars included in parsing a template
to the parameters of parseTemplate. This allows overriding of the
default leadingTriviaChars, which is needed by some pipelines like the
indexing pipeline because leadingTriviaChars may throw off the recorded
span of selectors.
