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.

* In a few places where we expect the type to implicitly cast to a

I added access to the `.sem` member of the TypePair. I tried adding an

This makes the .cc files match the header file name, which allows for
the text editor "header flip" feature to actually work. The reason these
files were named this way was because GN doesn't allow name conflicts in
the same source set, despite the files being in different directories.
This change splits the files into different source sets. To do so, we
use GN templates, which also reduces duplication in each target
definition.
