Language Server improvements. (#2269)

* Language Server improvements.
- Improve parser robustness around `attribute_syntax`.
- Exclude instance members in a static query.
- Coloring accessors
- Improved signature help cursor range check.

* Add expected test result.

* Language server: support configuring predefined macros.

* Fix constructor highlighting.

* Improving performance by supporting incremental text change notifications.

* Fix UTF16 positions and highlighting of constructor calls.

* Add completion suggestions for HLSL semantics.

* Fix tests.

* Fix: don't skip static variables in a static query.

* Include literal init expr value in hover text.

* Fix scenarios where completion failed to trigger.

* Fixing language server protocol field initializations.
