MLBEDSW-5102 Update removal of memory only operators

Memory only operators such as Reshape, Squeeze and ExpandDims are
removed in the graph optimiser step.

- Added semantic check that memory only operators have same
  quantisation parameters on ifm/ofm.
- Added support for the ExpandDims operator.
- Addition and cleanup of related unit tests.
- Removed TOSA from the generated SUPPORTED_OPS.md documentation.
