4f4534df3a Enable InsertBefore to work on global declarations
Use it for entry point IO sanitizing transforms to fix cases where structures were being inserted before type aliases that they reference.

Also fixes up some ordering issues with the FirstIndexOffset
transform.

3549e2ea8c Resolver: Enforce vector constructor type rules
Added enforcement for vector constructor type rules according to the
table in https://gpuweb.github.io/gpuweb/wgsl.html#type-constructor-expr.

This surfaced a number of existing tests that violated some of these
rules or had a type-declaration related bug, so this CL fixes those as
well (these tests either passed the incorrect number of arguments to a
vector constructor or relied on implicit conversions between numeric
types).

cf79a16fef [hlsl-writer] Handle non-struct entry point parameters
Add a sanitizing transform to collect input parameters into a
struct. HLSL does not allow non-struct entry-point parameters, so any
location- or builtin-decorated inputs have to be provided via a struct
instead.

5b36d2c612 Remove all unnecessary includes
All includes from .cc to .h are preserved, even when transitively included.

It's clear that there are far too many includes in header files, and we should be more aggressive with forward declarations. tint:532 will continue to track this work.

There are, however, plenty of includes that have accumulated over time which are no longer required directly or transitively, so this change starts with a clean slate of *required* includes.

eb496d0a4d transform: API cleanup
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.
