Program is now immutable*, and remains part of the public Tint
interface.
ProgramBuilder is the mutable builder for Programs, and is not part of
the public Tint interface. ast::Builder has been folded into
ProgramBuilder.
Immutable Programs can be cloned into a mutable ProgramBuilder with
Program::CloneAsBuilder().
Mutable ProgramBuilders can be moved into immutable Programs.
* - mostly immutable. It still has a move constructor and move
assignment operator - required for practical usage - and the
semantic information on AST nodes is still mutable.

Enforce all places where Dawn passes in or returns a ast::Module, now takes a `const Program* ` or returns a `Program`.
As the end goal of all this is to have immutable Programs, all Program inputs take a pointer instead of moving the actual object.
As consumers of a Program are now all const, we have to const_cast to work around all the places we've been incorrectly mutating a ast::Module.
These const_casts are temporary, and will be fixed in the next set of changes.
Depends on https://dawn-review.googlesource.com/c/dawn/+/38522

The reason being that some tests called parse() twice, which will silently destruct the first parser.
Once the `Module` owns the AST nodes, the second call will end up deleting all the AST nodes. Tests would then perform use-after-free for the AST nodes belonging to the first parser / module.
There's no reason why the unique_ptr can't be returned, which is cleaner overall.

(I expect that) the WGSL signed division operator expects both operands
to be signed and the result will also be signed.
When the operands of a SPIR-V OpSDiv is unsigned, then wrap
the operand in an as-cast to the corresponding signed type.
When the result type of a SPIR-V OpSDiv instruction is unsigned,
we have to wrap the generated WGSL operator with an as-cast to
that unsigned type.
This first CL addresses OpSDiv. We'll address other operations in future CLs.
