A number of tests check the first encountered error is correct.
As the parser currently aborts after the first error, later errors are ignored.
Once the parser supports resynchronization, we'll emit multiple error messages, and these tests will start to fail. Fix them now.

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.

`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.
