MLBEDSW-6716: Updates to estimate op SRAM usage

- The cascade builder estimates how much SRAM usage an operator
takes when calculating the cascades. If an elementwise operator
is included in a cascade the IFM2 will always be a constant/scalar
and the IFM2 will be in permanent memory and the size of the
IFM2 should not be included in the SRAM estimate.

- The scheduler did not take into account that IFM can be reused
for the OFM when calculating the op memory usage resulting in
a negative number for non-local memory usage. Corrected the
calculation and added assert to detect future problems.
