Ben Clayton 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.

Ben Clayton 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.

Ben Clayton 88dc2a4895 wsgl parser: Unify logic for all decorations
Parse all decorations with the same function, and create a
`ast::DecorationList`. Once the parser has progressed to the consumer of
the decorations, we attempt to downcast these to the required type,
erroring if they're the wrong kind.

While the error message could be improved further, this greatly reduces
the headscratching around crbug.com/tint/291.

Also knocks another 223 lines off parser_impl.cc.

Ben Clayton 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.

`StructDecoration` has been transformed from an `enum class` to a proper class so it can derive from `Decoration`.

Ben Clayton ecea5c8aec Make Formatter a non-interface
I had originally created `Formatter` as an interface as I was intending to implement this differently for linux and windows (for terminal coloring).

Color printing is instead implemented by the `Printer` interface / PIMPL classes.

Replace the multi-boolean constructor with a `Style` struct, as this will make life easier when we want to add / remove flags.

Ben Clayton 5bee67fced Add File & Range information to tint::Source
This is the first step in improving the error messages produced while parsing.

The `line` and `column` information of `Source` has been moved to `Source::Location`.

`Source::Range` has been added that contains a `Location` interval - allowing error messages to highlight the full region of the error.

The `File` information provides an optional file path, and pre-splits the content into lines. These lines can be used to print the full line containing an error.

This CL contains a few temporary changes that help split up this work, and to ease integration with Tint.
