Subject: Fix for default initialization with generic field (#2168)

* #include an absolute path didn't work - because paths were taken to always be relative.

* Fix for = {} initialization with a field that is generic type parameter.

* Handling for if a non type is passed to a generic parameter which requires a type.

* Small comment improvements.
Fix some tab issues.

* This fixes the matrix.slang issue. Move the matrix.slang test into bugs as generic-default-matrix.slang
