SET KERNEL only copies the first byte

[jrprice]

SET KERNEL only copies the first byte of the kernel argument to the buffer. Reproducer script:

kernel void foo(global int* out, int value) {
  *out = value;
}
END

BUFFER out_buf DATA_TYPE uint32 DATA 0 END

PIPELINE compute p1
  ATTACH my_shader ENTRY_POINT foo
  BIND BUFFER out_buf KERNEL ARG_NAME out
  SET KERNEL ARG_NAME value AS int32 300
END

RUN p1 1 1 1

EXPECT out_buf IDX 0 EQ 300

Running this yields:
Line 32: Verifier failed: 44 == 300, at index 0
(44 is 300-256)

I believe this is because the buffer is created as R8_UINT, and the Buffer::SetDataWithOffset(Value) method uses the format to determine how many bytes to copy to the buffer, not the size of the values passed to it.
