Semantic information about block statements the resolver would
temporarily create while resolving is now exposed in a
sem::BlockStatement class.
In the process, semantic information about statements in general is
overhauled so that a statement has a reference to its parent
statement, regardless of whether this is a block.

In preparation for implementing
https://github.com/gpuweb/gpuweb/issues/1604, this change removes the
sem::AccessControl node. Instead, the ast::AccessControl::Access enum is
now on the sem::StorageTexture class, as well as on sem::Variable. For
sem::Variable, the field is set when the variable's type is either a
storage buffer or a storage texture.

Add a new parameter to BindingRemapper::Remappings that allows resulting binding points to collide.
When enabled, the output of the transform contains two or more module-scoped variables with the same binding point, used by the same entry point, then these variables will be decorated with an internal decoration to disable validation for the collision.
This is to work around collisions generated for the HLSL backend where the variables actually exist in different register classes, which is permitted by D3D12.
The transform will only generate these decorations if it needs to.
