vela: Improve block configuration and weight buffering algorithm
- Update block config selection to take into account partial
IFM fetches at edge of non-whole OFM block data.
- Change to scheduler depth slicing for networks in MLBEDSW-4637
for improved buffering. This helps general performance by buffering
larger depth slices.
- Bug fix for opt_max_schedule always being fitted to SRAM which
prevented the optimisation step running in some cases.
