- Refactored erroneously if statement that allowed illegal
swapping between ifm1 and ifm2 for elementwise operators.

- The cascade builder is using the ifm_ifm2_correct_order
function in order to decide if the operator is cascadable or not.
The problem is that this function expects a full shape or no shape
and the cascade builder did not provide that, so the operator was
reported to be non cascadable.
- The fix is to provide a full 4D shape, also refactoring
ifm_ifm2_correct_order to use 4D shape to avoid confusion
in the future.
- Refactoring code so that the scheduler can perform a
correct ifm and ifm2 swap.

The problem was that the updated conditions for elementwise
cascading was to permissive after the RescaleAdd removal.
Conditions for elementwise updated and transpose convolution
removed from cascading since it does have issues.

Removed RescaleAdd and RescaleMul operators in favour of
Operation.explicit_scale and removed Operation.rescale.

Remove resize ops completely from being cascaded since there
are corner cases which are not currently handled.

- When compiling for shared SRAM the old scheduler has an option so
that it produces less SRAM than what the new scheduler manages to
produce. The old scheduler was able to creates more/longer cascades.
In order to improve the new scheduler, the following has been
implemented:
- Take persistent IFM's into account when creating the min schedule.
- Choose longer cascades when it is possible to reduce the total
SRAM usage compared to using shorter cascades.
- Updated calculation for estimated SRAM usage for elementwise ops.

Uses separate tensors for the individual weight buffers
in case of weight double buffering.
Each weight buffer tensor gets its own individual live range.
This patch is a clone of a previously reverted patch, but with some
additional bug fixes applied.

- Cascading a slice operator with read offsets is not
supported by the rolling buffer mechanism causing the
address to get out of range.
- The fix is to prevent ops to be cascaded if they have
read offsets.

Bug fix in cascade builder: tensors produced with operators requiring full OFM
or consumed by operators requiring full IFM could be added as intermediate buffers
to a cascade.
