Instead of using an `if` node that has a list of `else` statements,
make each `if` statement have a single optional `else` statement,
which may itself be an `if` statement (or just a block statement).
This better matches the WGSL grammar (now that we have removed
`elseif`), and simplifies various pieces of code that handle these
statements.

With creation-time expressions, we'll need to add `const` declarations.
Note that module-scope `let` declarations have been removed in the spec (for `const`). ProgramBuilder::GlobalConst() has not been renamed, although it still currently produces 'let' declarations.

In this CL the enable directive is implemented.
1. Add AST node for enable directive, assign a ExtensionKind (enum) for
each supported extension.
2. Use an unorder_set in ast::Module to record all required extensions'
kind.
3. Provide inspector methods for getting names of used extension, and
getting all used enable directives' extension names and location.
4. For different writer, the extension nodes are handled in different
ways. MSL and HLSL writers will just ignore the extension nodes, while
SPIRV and GLSL writers will emit corresponding code.
5. Implement unittests and end2end test for enable directive and
inspector, using a reserved extension name `InternalExtensionForTesting`.

In our backends, we std::move this unordered_set into the Results
struct, but because we'd get a const reference to a const object,
std::move would cast this to a const r-value, which binds to const ref,
and thus would end up copying instead of moving. This change just
ensures that we get a non-const ref to a non-const unordered_set where
we do the move.

This transform converts compound assignment statements into regular
assignments, hoisting LHS expressions and converting for-loops and
else-if statements if necessary.
The vector-component case needs particular care, as we cannot take the
address of a vector component. We need to capture a pointer to the
whole vector and also the component index expression:
// Before
vector_array[foo()][bar()] *= 2.0;
// After:
let _vec = &vector_array[foo()];
let _idx = bar();
(*_vec)[_idx] = (*_vec)[_idx] * 2.0;
