Previously Hashmap used to internally use a Hashset which held entries
of key-value pairs. This was cute, but meant that a Hashset held mutable
entries, which was a bag-of-bugs waiting to happen (change the entry to
hash as something different and you're now in an entirely broken state).
Pull the complex bits of Hashset out to HashmapBase, and have both
derive from that. I've opted for inheritance over composition here to
reduce the amount of structure chasing you'd have to do without
debugger pretty-printers.

Since GLSL ES does not support the offset= attribute, struct members
with explicit @align or @size attributes require adding explicit
padding members. This in turn requires rewriting any constructor
calls to initialize the new padding to zero, handled in the same
transform.
Note that this is currently overly-verbose, and will add padding where
GLSL doesn't technically need it (e.g., padding a vec3 out to 16 bytes).

This uses template and macro magic to reflect the fields of a class.
Dawn:
* Reflect the fields of the types that are used by Dawn's stream::Stream<T> specializations, and use tint::ForeachField() to call StreamIn().
Fuzzers:
* Replace tint::fuzzers::DataBuilder::BuildImpl<T> specializations with the new reflection system.
* static_assert that the type is either POD or reflected. Add a specialization for std::optional which was missing.
Move tint::transform::BindingPoints into MultiplanarExternalTexture, as this is only used by MultiplanarExternalTexture.
All this reduces fragility of the struct declarations slipping out of sync with the uses.

Extract out the methods of Resolver::EvaluateXXXValue() to a new

Change sem::Constant to be an interface to the constant data. Implement
this so that zero-initialized data doesn't need to allocate the full
size of the type.
This also makes usage a lot cleaner (no more flattened-list of
elements!), and gives us a clear path for supporting constant
structures if/when we want to support them.

This is required, as the backends will inline variables that resolve to

And remove the WrapArraysInStructs transform.
Wrapping arrays in structures becomes troublesome for `const` arrays, as
currently WGSL does not allow `const` structures.
MSL 2.0+ has a builtin array<> helper, but we're targetting MSL 1.2, so
we have to emit our own. Fortunately, it can be done with a few lines of

Implement new transform UnwindDiscardFunctions that replaces discard
statements with setting a module-level bool, adds a check and return for
this bool after every function call that may discard, and finally
invokes a single function that executes a discard from top-level
functions.
Regenerated tests and remove HLSL ones that used to fail FXC because it
had difficulty with discard.

We still use the StrideAttribute AST node in the SPIR-V reader for
strided arrays and matrices, which are then removed by transforms.
The WGSL parser no longer has to handle attributes on types.
