dan sinclair a7e1492a6a [wgsl-reader][wgsl-writer] Support new sampled texture syntax.
This CL updates Tint to support the `texture_1d` format for sampled
textures. This is alongside the old `texture_sampled_1d` to allow
migration time.

The WGSL writer will always output the new form when converting to WGSL.

This is the first step in unifying the way decorations are parsed - i.e. instead of parsing decorations in different ways based on the predicted grammar that follows, we can parse decorations blocks in a unified way, then later verify what we have is as expected.

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

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.

dan sinclair bfc2fceb84 Use min for bounded array accessing.
This CL updates the BoundArrayAccess transform to use `min(u32(val),
size)` instead of `clamp(val, 0, size)` so as to reduce the number of
instructions needed to clamp within range.
