WGSL:
* Remove vertex_idx and instance_idx.
These are now vertex_index and instance_index.
It seems this was removed once before, then reverted due to CTS
failures, but the original change never landed again.
* Remove the [[set(n)]] decoration. This has been [[group(n)]] for
months now.
API:
* Remove deprecated enums from transform::VertexFormat.
* Remove transform::Renamer constructor that takes a Config. This should
be passed by DataMap.
* Remove ast::AccessControl alias to ast::Access.
