scripts: add --partition-size feat to sd_fusing.py

The idea is to alter partition sizes via
overriding part_table prior to SdFusingTarget.__init__
to avoid hardcoding it every time you need such a change.

Implemented in SdFusingTarget.apply_partition_sizes

Currently only called (and tested) for RV64 target
