d8857d55 - [mlir][tosa] Check for isolated regions in `tosa.while_loop` (#144865)

[mlir][tosa] Check for isolated regions in `tosa.while_loop` (#144865) Similarly to `tosa.cond_if`, this patch checks that the cond/body regions of `tosa.while_loop` are isolated from above. This is required since the specification requires all values used in the cond/body regions are explicitly declared within the regions.
