  Log Message:
  -----------
  [DirectX] Add support for typedBufferLoad and Store for RWBuffer<double2> and RWBuffer<double> (#139996)

typedBufferLoad of double/double2 is expanded to a typedBufferLoad of a
<2 x i32>/<4 x i32> and asdouble
typedBufferStore of a double/double2 is expanded to a splitdouble and a
typedBufferStore of a <2 x i32>/<4 x i32>
Add tests showing result of intrinsic expansion for typedBufferLoad and
typedBufferStore
Add tests showing dxil op lowering can handle typedBufferLoad and
typedBufferStore where the target type doesn't match the typedBufferLoad
and typedBufferStore type
Closes #104423
