This commit adds support to the TagHelperBinderSyntaxTreePass to interpret
@addTagHelper, @removeTagHelper, and @tagHelperPrefix.
I also ported all the original tests for this feature and updated them to
call new APIs.
The bulk of the changes here were updates to baseline tests that weren't
correctly using @addTagHelper
- Previously we'd special case `@section` at code generation time; now we transform the directive into an IR node.
- Changed the expectations of `DefineSection` to not take in a section writer. It's now expected to modify what `Write`, `WriteLiteral` etc. write to when inside of the lambda. This is done today in TagHelpers via `StartTagHelperWritingScope`.
- Updated baseline files to reflect new `DefineSection` expectations.
- Updated IR tests since we no longer leave around `DirectiveIRNode`s.
#901
- Removed the `CreateReader` API in favor of a `CopyTo`, `Length`, `[index]` and `Encoding`.
- Updated existing APIs to react to the change.
- Added tests.
This is an API skeleton for the IR data model that we'll be using as a
spiritual continuation of the 'chunks' API. Currently missing a lot of
detail which will be filled in as needed.
