[PR] [WebGPU] Translate `int8x4` into `u32` [tvm]
Jiawei-Shao opened a new pull request, #17071:
URL: https://github.com/apache/tvm/pull/17071
This patch translates an `int8x4` into a `u32` in WGSL shaders as 8-bit integers are not supported in WebGPU right now and the WGSL built-in function `dot4I8Packed()` accepts `u32` as its inputs and each of the `u32` value logically represents a 4-element 8-bit integer vector.
issue: #16627
