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.

With the addition of the AccessControlType we want to look through the
