HLSL-IR: implement extractBits full polyfill

Implemented as a general polyfill, but only used by the HLSL backend
currently.

Tested CTS using dawn_node with `-use-ir` and the following now pass:
`webgpu:shader,execution,expression,call,builtin,extractBits:*`
`webgpu:shader,validation,expression,call,builtin,extractBits:*`
