Initial `dyn` keyword support & `-lang 2026` compiler option (#7172)
fixes: [#7143](https://github.com/shader-slang/slang/issues/7143)
fixes: [#7146](https://github.com/shader-slang/slang/issues/7146)
Goal of PR:
* This PR is part of the larger #7115 refactor to how dynamic dispatch works.
* The first step is to add the `-std <std-revision>` flag.
* The second step is to provide basic `dyn` keyword support in AST. This does not include `varDecl` support since most of these interactions require `some` keyword support.
Future PR(s) goal:
* Support `some` keyword in AST. With this we will also implement all varDecl interactions between `dyn` and `some`.
* Add IR support for `some` and `dyn`.
Breakdown of PR:
* most of the logic is in `validateDyn.*`. This was done so that in the future when we implement more features we will have an easy time removing/adding restrictions to `dyn` interfaces.
Breaking changes:
* As per spec (https://github.com/shader-slang/spec/pull/14/files), any type conforming to a `dyn` interface errors if member list contains one of the following: opaque type, non copyable type, or unsized type.
* Due to the breaking change, the test `tests\compute\dynamic-dispatch-bindless-texture.slang` is incorrect. This has been fixed.
