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.

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.
