* Moved global variable resolving logic to new function Resolver::GlobalVariable, and moved validation logic there.
* Moved global variable-related tests to resolver tests.
* Fixed many tests that started failing after this change, mainly because many globals were declared with no storage class. I set most of these to "Input".

This performs very basic type verification for assignments and variable initializers.
Pulls part of the validation logic out of the Validator into the Resolver.
Involves fixing up a bunch of broken tests.

* Moved Validator::ValidateConstructedType, which only validated
structs, to Resolver as ValidateStructure.
* Moved relevant tests to new files, and also updated all failing tests
to validate Source location.
* Fixed other tests that broke now that we're validating structs.

This change validates that the operand types and result type of every
binary operation is valid.
* Added two unit tests which test all valid and invalid param combos. I
also removed the old tests, many of which failed once I added this
validation, and the rest are obviated by the new tests.
* Fixed VertexPulling transform, as well as many tests, that were using
invalid operand types for binary operations.

Transforms are meant to be reusable. Those that hold state cannot be used concurrently.
State leakage between runs is dangerous.
To fix this:
* Add transform::Data - A new base class for extra information emitted by transforms.
* Add transform::DataMap - A container of Data, keyed by type.
* Add a transform::DataMap field to Transform::Output.
* Have FirstIndexOffset emit a FirstIndexOffset::Data.
* Deprecate the getters on the transform.
Mutability of the transform config is also dangerous as setters can be called while a transform is actively running on another thread.
To fix:
* Expose a VertexPulling::Config structure and add a constructor that accepts this.
* Deprecate the setters on VertexPulling.
Also deprecate Transform::Output::diagnostics.
Put all the transform diagnostics into the returned Program. Reduces error handling of the client.

Instead of emitting all global variables and then functions, emit
global declarations in the order they were added to the AST.
This fixes issues where the reording might generate an invalid WGSL
program from a valid input (e.g. when declaring a global variable with
the same name as a variable inside a function that precedes it).
This also unifies the implementation of Generate() and
GenerateEntryPoint(), to avoid implementing the same logic twice.

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).
