Ben Clayton 35298800a6 ast: Have all decorations derive from base class
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`.

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.

Ryan Harrison 1a9a2dd07d Add Inspector class
This class is used to examine a module and get information about its
contents. This is the getting side of shader of reflection. Future
work will add transforms that perform the setting side of reflection.

In addition to the basic class and infrastructure, this CL adds a
GetEntryPoints() function demonstrate it works. More functionality
will be added in later CLs.
