Add reflection API for functions. (#4587)

* Add reflection API for functions.

This change adds `SlangFunctionReflection` type in the reflection API that provides methods for querying function result type, parameters and user-defined attributes.

`ProgramLayout::findFunctionByName` can now find a function with the given name and returns a `FunctionReflection`.

`IEntryPoint` now has a `getFunctionReflection` method that returns an `FunctionReflection` for the entrypoint.

* More modifiers; make reflection API consistent.
