Add `transform::DecomposeStridedMatrix`, which replaces matrix members of storage or uniform buffer structures, that have a [[stride]] decoration, into an array
of N column vectors.
This is required to correctly handle `mat2x2` matrices in UBOs, as std140 rules will expect a default stride of 16 bytes, when in WGSL the default structure layout expects a stride of 8 bytes.

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.

Move the bulk of the constant evaulation logic out of transform::FoldConstants and into Resolver and sem::Expression.
transform::FoldConstants now replace TypeConstructor nodes that have a constant value on the expression.
This is ground work to:
* Cleaning up the HLSL uniform buffer indexing, which is `/` and `%` arithmatic heavy
* Prepares us to handle `constexpr` when it lands in the spec
* Provide a centralized place to do constant evaluation, instead of the
having similar logic scattered around the codebase.

And remove the u32 overload of frexp (it's not in the spec).
Brings the number of failing tint end to end tests for MSL down to 19/1098.
The WG still haven't found consensus on reworking these two intrinsics.
It's very likely that their signature will change so that they return a structure instead of returning a value and outputing another as a pointer.
Until the WG makes a decision, let's implement these according to the current spec.
Some overloads are still failing due to MSL missing overloads of the pointer parameter being in the `threadgroup` address space.
I'm holding off fixing these until we know what's happening with these intrinsics.
