Adds support for the new shader IO syntax by processing entry
parameters and pushing them to function-scope variables as necessary.
Module-scope variables are still supported for now.

Variables in the storage storage class and variables with a storage
texture type must have an access attribute applied to the store type.
https://gpuweb.github.io/gpuweb/wgsl/#module-scope-variables
A variable in the storage storage class is a storage buffer variable. Its
store type must be a host-shareable structure type with block attribute,
satisfying the storage class constraints.
Fixup tests, including those that were producing warnings about `var <in>`
The WGSL writer seems to want to put a newline after every decoration block, leading to some ugly output. I'll fix this as a separate change.

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.
