This is a reland of a57c1db878e2f8a7eb352c8f253db5488cdca6f6
in current Dawn implementation RenderPipelineGL and ComputePipelineGL
will be destroyed before calling their initialize() function when we
can find a proper pipeline object in the front-end cache, so mProgram
may not be assigned to a valid GL program ID when the destructor of
PipelineGL is called.
In this CL we always initialize mProgram to 0 in the constructor of
PipelineGL so that it won't be a garbage value in the destructor of
PipelineGL (0 is safe for glDeleteProgram() according to OpenGL SPEC).
Original change's description:
> OpenGL: delete shaders and pipelines when they are not used any longer
>
> Previously on OpenGL backend the GL pipelines and shaders are never
> deleted. With this patch the GL pipelines and shaders will be able to

Every render pass which invokes DrawIndexedIndirect, either directly or
through a RenderBundle execution, is now preceded immediately by at
least one validation pass.
All indirect buffer offests used with DII are validated, and their
validated values are copied into a separate scratch buffer (or zeroed
out there, in the case of validation failure). All encoded DII commands
are rewritten to use the validated parameters instead of the original
ones.

This is a simple RefCounted holder of a Buffer ref and offset. Encoded
commands can store a ref to this object instead of directly storing an
inline Buffer ref and offset, allowing other commands to dynamically
patch in a different buffer+offset as needed, in a memory-safe way;
as opposed to e.g. retaining an unmanaged pointer to the encoded
command itself and modifying it in-place.
Validation commands will use this to rewrite buffer references in
encoded commands, so that they execute over validated inputs rather
than over their original client-provided inputs.
No net functional changes in this CL, just some groundwork for indirect
draw/dispatch validation.

This command copies data from host memory into a GPU buffer. It's
analogous to Queue::WriteBuffer, but executed in the context of a
command buffer, sequenced with other encoded commands. This is useful
for supporting a notion of a shared scratch buffer, with a single

before each pass that uses it.

Buffer allocations in Dawn may be padded. This padding
could be visible, depending on how the backend
implements robust vertex buffer access. This commit
updates buffer creation to clear all padding bytes
immediately after creation.
It is not counted as a lazy clear.
And, add a test which reads off the end of a padded
vertex buffer to check that the padding bytes are also
initialized.
Also: Update Metal buffers to always allocate enough
space for Tint's vertex pulling, and pass the full
allocated size to Tint. While writing the test in this
commit, a bug was found where Tint assumes there is at
least 4 bytes in the vertex pulling buffer. The WebGPU
API currently allows zero-sized bindings, so Dawn needs
to always allocate enough space for one element.
Also: Update Vulkan vertex/index buffers to allocate
at least one more byte than requested because
vkCmdSetVertexBuffers and vkCmdSetIndexBuffer disallow
the offset to be equal to the buffer size. We need
at least one more byte to make zero-sized bindings
as the end of the buffer valid.
Lastly: Update helper so that a T2B copy of a single
row that touches all bytes in a buffer updates the
buffer state to be fully initialized. This is a small
optimization that is necessary to write the test.

Tint now has a single-function API for code generation that
automatically runs the backend-specific sanitizer transforms. This API
allows for backend-specific configuration options such as the fixed
sample mask for MSL (and, in the future, information about which
compiler/version is being targeted), and returns any backend-specific
metadata such as whether a UBO of buffer sizes is required by the
shader.
This change prevents the post-sanitizer program from being exposed to
Dawn, which is a potential foot-gun (e.g. the Inspector is not
expected to be run after the sanitizer transforms, and Dawn is
currently doing this).
The old Generator class API will be removed from Tint shortly after
landing this change.

Below are the list of all the individual changes, which are a good order
in which to review this CL.
Core changes:
- Change the tracking in the frontend to produce a synchronization
scope per dispatch instead of per compute pass. Some bindgroups might
not be part of any synchronization scopes so we also track all the
referenced resources on the side so they can be checked during
Queue::Submit validation.
- Fix clearing in the GL and Metal backends to use the per-dispatch
synchronization scopes.
- Fix the Vulkan backend to use the per dispatch synchronization scopes
to produce the correct pipeline barriers. This allows the removal of
previous logic that was subtly incorrect for Indirect buffer. This
allows the merging of the Compute and Render DescriptorSetTracker into
a single small helper class.
- D3D12 changes are similar to Vulkan, but the simplification is just a
the suppression of a branch with a lot of code in
BindGroupStateTracker.
Test changes:
- Fixup all the ResourceUsageTracking tests to follow the WebGPU spec
for synchronization scopes (fixing a lot of TODOs).
- Add additional tests checking that Indirect buffers are not allowed
to be used as a writeable storage in the same synchronization scope.
- Add tests for Queue::Submit validation correctly taking into account
resources that are bound but unused in compute passes.
- Add an end2end test for using a buffer as Indirect and Storage at the
same time in a DispatchIndirect, which would previously produce
incorrect barriers in the Vulkan and D3D12 backends.
Other small changes (that I was to lazy to put in a different CL):
- Add the utils::MakePipelineLayout helper function.
- Fix Indirect not being in the list of readonly buffer usages (caught
by a test added in this CL).
