Generate a uniform buffer that will receive the lengths of all storage
buffers, and use this to implement calls to arrayLength(). The
transform is provided with a set of mappings from storage buffer
binding points to the corresponding index into the array of buffer
lengths. The transform reports whether it generated the uniform
buffers or not.
Use this transform from the MSL sanitizer, using the binding number as
the index into the array. This matches the behavior of spirv-cross,
and so works with how Dawn already produces this uniform buffer.

HLSL requires that each structure field in a UBO is 16 byte aligned.
WGSL has much looser constraints with its UBO field alignment rules.
Instead generate an array of uint4 vectors, and index into this, much
like we index into [RW]ByteAddressBuffers for SSBOs.
Extend the DecomposeStorageAccess transform to support uniforms too.
This has been renamed to DecomposeMemoryAccess.

Handle access control on var declarations instead of via [[access]]
decorations. This change does the minimal work to migrate the WGSL
parser over to the new syntax. Additional changes will be needed
to correctly generate defaulted access qualifiers, as well as
validating access usage.
The [[access]] decorations are still supported by the WGSL parser,
with new deprecated warnings, but not for aliases. Example:
var x : [[access(x)]] alias_to_struct;
Making this work is far more effort than I want to dedicate to backwards
compatibility, and I do not beleive any real-world usage will be doing
this.
Still TODO:
* Adding access control as the optional, third parameter to ptr<>.
* Calculating default accesses for the various storage types.
* Validating usage of variables against the different accesses.

This reverts commit 594075a2f0.
Reason for revert: This is not a complete solution. It does not cover assignment of variables of the same struct type, but of different access types. For example:
```
[[block]] struct S{ i : 32; };
var<storage> gr : [[access(read)]] S;
var<storage> gw : [[access(write)]] S;
fn f() {
var a : S;
a = gr;
gw = a;
}
```
With my CL, we currently generate invalid assignments because the new types of 'S' for 'gr' and 'gw' are now all different types. We would need to generate functions to assign between them.
In the end, we will drop this strategy, and instead, Dawn will be modified to not rely on names.
