Remove the old backend specific implementation for overrides. Use tint SubstituteOverride transform to replace overrides with const expressions and use the updated program at pipeline creation time. This CL also adds support for overrides used as workgroup size and related tests. Workgroup size validation now happens in backend code and at compute pipeline creation time.

{# Helper macro to render readers and writers. Should be used in a call block to provide additional custom
|
|
handling when necessary. The optional `omit` field can be used to omit fields that are either
|
|
handled in the custom code, or unnecessary in the serialized output.
|
|
Example:
|
|
{% call render_streaming_impl("struct name", writer=true, reader=false, omits=["omit field"]) %}
|
|
// Custom C++ code to handle special types/members that are hard to generate code for
|
|
{% endcall %}
|
|
One day we should probably make the generator smart enough to generate everything it can
|
|
instead of manually adding streaming implementations here.
