* move bin/naga.rs to a separate crate

* enable all shader languages for naga binary

* [naga-cli] add env logger

* [naga-cli] remove unneccessary code

* [naga-cli]enable glsl-validate feature

* move naga-cli to cli, add trailing newline

* remove commented env_logger dependency

Adds support for workgroup size and early fragment tests definitions

Nobody uses that value. This lets us simplify `GlobalVariable` and
`write_global_variable` as well.

* [glsl-out] Fix writing named expressions with array types

* [wgsl-out] Remove unsupported builtin from baked expression

* [glsl-out] Add a newline between globals for readability

* Set bake_ref_count to 1 for Expression::Load

* Update snapshot data

In tests/out, stop generating the uncommitted files quad-glsl.ron and
quad-glsl.spvasm, and add the snapshot quad-glsl.wgsl.

This makes Naga IR validation impose the restrictions added to WGSL in
gpuweb/gpuweb#1801.

Remove code in the SPIR-V writer to spill arrays to temporary variables in order
to index them dynamically. If such IR is encountered, treat it as a failure of
validation.

* [glsl-in] Add glsl snapshots folder

* [glsl-in] Fix incorrect angle brackets parsing

* [glsl-in] Temporarily remove wgsl snapshot output

Adds a check of wether or not a global can be read in the entry point prologue
