Adds a "tag" system so that entries of dawn.json can be conditionally
emitted in different configurations. With a few more dawn.json changes,
this will enable generating the exact upstream header.

For HLSL, use the new NumWorkgroupsFromUniform transform, and expose
the binding point to use for the generated uniform as a backend
option.
The MSL mapping is trivial, and it was already implemented for WGSL
and SPIR-V.

Change ast::Array to use an ast::Expression for its `size` field. The
WGSL frontend now parses the array size as an `primary_expression`,
and the Resolver is responsible for validating the expression is a
signed or unsigned integer, and either a literal or a non-overridable
module-scope constant.
The Resolver evaluates the constant value of the size expression, and
so the resolved sem::Array type still has a constant size as before.

This chained struct can be used for internally adding usages to
Dawn textures. It will affect how the texture is allocated, but
not affect frontend validation.
One use case for this is so that Chromium can use an internal
copyTextureToTexture command to implement copies from a WebGPU
texture-backed canvas to other Web platform primitives when the
swapchain texture was not explicitly created with CopySrc usage
in Javascript.
Usage:
wgpu::DawnTextureInternalUsageDescriptor internalDesc = {};
internalDesc.internalUsage = wgpu::TextureUsage::CopySrc;
wgpu::TextureDescriptor desc = {};
// set properties of desc.
desc.nextInChain = &internalDesc;
device.createTexture(&desc);

This change introduces sem::CompoundStatement, a new base class for
statements that can hold other statements.
sem::BlockStatements now derives from sem::CompoundStatement, and
this change introduces the following new CompoundStatements:
* `sem::IfStatement`
* `sem::ElseStatement`
* `sem::ForLoopStatement`
* `sem::LoopStatement`
* `sem::SwitchStatement`.
These new CompoundStatements are now inserted into the semantic
tree as now documented in `docs/compound_statements.md`.
The `sem::BlockStatement::FindFirstParent()` methods have been
moved down to `sem::Statement`.
The `Resolver::BlockScope()` method has been replaced with
`Resolver::Scope()` which now maintains the `current_statement_`,
`current_compound_statement_ ` and `current_block_`. This
simplifies statement nesting.
The most significant change in behavior is that statements now
always have a parent, so calling Block() on the initializer or
continuing of a for-loop statement will now return the
BlockStatement that holds the for-loop. Before this would
return nullptr.

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 CL adds two helpers for more ergonomic processing of
ChainedStructs.
1. FindInChain(): Iterates through the chain and automatically
casts the ChainedStruct into the appropriate child type before
returning.
2. ValidateSTypes(): Verifies that the chain only contains structs
with sTypes from a pre-defined set. This also allows the caller
to specify one-of constraints.
3. ValidateSingleSType(): Verifies that the chain contains a
single struct with a specific sType or is an empty chain. This
is a common case of |ValidateSTypes()| and is separated out as
a fast-path.

Remove all usages of SPVC from the code and update the fuzzers. Some
of the include paths and deps came transitively from spvc, so needed
to update build rules.
This patch does NOT remove the flags related to spvc usage, they are
just no-ops as the moment. After this patch lands I will remove the
usage of those flags from the bots, then remove the flags.
