This CL reverts the changes to use the top level namer in the various
backends. This is causing issues when rolling into Dawn in the case
where the tint generator is used to create SPIR-V which is sent to
SPIRV-Cross but then generator and inspector aren't used. The entry
points end up being incorrect as SPIRV-Cross gets the renamed entry
points.

This CL changes the generators so we don't have to move the module into
the generator. This will then allow calling the demangler at a later
point and still having access to the module.

instead of transform-in-place.
This is a public API breaking change, so I've added the `DAWN_USE_NEW_TINT_TRANSFORM_API` define which is used by Dawn to know which API to use.
As we're going to have to go through the effort of an API breaking change, use this as an opportunity to rename Transformer to Transform, and remove 'Transform' from each of the transforms themselves (they're already in the transform namespace).

EmitVertexPointSizeTransform is a Transformer that adds a PointSize builtin global output variable to the module which is assigned 1.0 as the new first statement for all vertex stage entry points.
If the module does not contain a vertex pipeline stage entry point then then this transformer is a no-op.

This CL removes all internal usage of the Context object. It is still
accepted as a parameter until we update Dawn, but all usage is removed.
The namer has been removed from the SPIR-V backend with this change and
the emitted names reverted to their non-modified version.

We've been using |blah| in various places to markup code, however this is not doxygen markup. So instead:
* If the code links to a parameter, use `blah`.
* If the code links to a member field, use #blah.
* If the code links to a method use blah().
* If the code is somewhere unlinkable use `blah`.

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.

This is located in include/tint/, so that users can have a pretty include of
