Ben Clayton c03a09c106 writer/hlsl: Rework string printing
Remove `pre` and `out` parameters from most generator methods.
Use the `out_` string stream in TextGenerator, add helpers to TextGenerator to simplify line printing.

Remove the `pre` and `out` fields from TestHelper.

Cleans up the `pre` aspects of the HLSL writer, so the same concept can be used by the MSL writer.
Fixes indentation bugs in formatting.

Vasyl Teliman 0b3611b8c8 Add spirv-tools fuzzer
This change adds a new tint fuzzer that uses SPIRV-Tools to fuzz SPIR-V binaries.
The fuzzer works on a corpus of SPIR-V shaders. For each shader from the corpus it uses
one of `spirv-fuzz`, `spirv-reduce` or `spirv-opt` to mutate and then runs the shader through
the Tint compiler in two steps:
- Converts the mutated shader to WGSL.
- Converts WGSL to some target language specified in the CLI arguments.

The list of all supported CLI arguments and their description is in the cli.h file.

James Price 14c0b8acbf Validate that in/out storage classes are not used
Use a DisableValidationDecoration to allow these storage classes only
for variables generated by the SPIR-V sanitizer. This is also used in
the Inspector tests, since the Inspector is currently run *after* the
SPIR-V sanitizer. These tests will be removed when this is no longer
the case.

Also validate that builtin/location decorations are not used on
variables (unless they have input/output storage class).

Fix or delete all of the other tests that were wrongly using these
storage classes and attributes.

David Neto 3d5453ce9c spirv-reader: remove builtin-inputs special cases
Remove special case handling of pointers and values related
to builtins SampleId, VertexIndex, and InstanceIndex.
These map to private variables with store type matching the
type stated in the SPIR-V code. There is no need to generate
special case code for user-written functions accessing those variables.

Therefore:
- Remove SkipReason enums associated with those builtin inputs
- Remove newly unreachable code.

James Price 960aa2ee75 msl: Add ArrayLengthFromUniform transform
Generate a uniform buffer that will receive the lengths of all storage
buffers, and use this to implement calls to arrayLength(). The
transform is provided with a set of mappings from storage buffer
binding points to the corresponding index into the array of buffer
lengths. The transform reports whether it generated the uniform
buffers or not.

Use this transform from the MSL sanitizer, using the binding number as
the index into the array. This matches the behavior of spirv-cross,
and so works with how Dawn already produces this uniform buffer.
