dd1b6fca9f Introduce semantic::Info
Will hold the mutable fields that currently reside in the otherwise immutable-AST.

Change the AST string methods to accept a `const semantic::Info&`. This is required as some nodes include type-resolved information in their output strings.

627732c408 src/reader tests: Have parse() return a unique_ptr
The reason being that some tests called parse() twice, which will silently destruct the first parser.
Once the `Module` owns the AST nodes, the second call will end up deleting all the AST nodes. Tests would then perform use-after-free for the AST nodes belonging to the first parser / module.
There's no reason why the unique_ptr can't be returned, which is cleaner overall.

0573714bfd wsgl parser: Have Expect & Maybe operator-> deref
For values of type T* and std::unique_ptr<T>.

This allows us to replace all occurances of `res.value->member` with: `res->member`, which also asserts that `res` is not in an error state.

Brings the verbosity back down to pre-expect and pre-maybe levels.

ab5dfee240 wsgl parser: Add ParserImpl::Maybe<T>
And use it for the non-ParserImpl::expect_xxx() methods.

Another step towards supporting multiple error messages, as the caller can now test to see if the specific call errored, or didn't match, instead of using a global error state.

Makes reading the control flow conditionals a bit easier too.

786bc92002 wsgl parser: Add expect_block(), use it
`expect_block()` takes a start and end token, along with a function to parse a lexical block body.

This reduces code, keeps error messages consistent, and also gives us a future place to try resynchronising the parser so we can have more than one error emitted.

`expect_paren_block()` and `expect_brace_block()` are convenience helpers for providing the start and end tokens for common block types.
