feat(weights-diff): Add memory weights

[ukint-vs]

Add comparison for memory weights.

cargo run --package gear-weight-diff --release -- diff ./weight-dumps/master.json  ./weight-dumps/vs-refine-runtime-interface.json "gear" "memory" --display-units

For example:

Comparison table for Gear runtime

We have a diff script that prints all types of weights

gear/scripts/weight-diff.sh

Lines 54 to 55 in c28aa50

	cargo run --package gear-weight-diff --release -- diff "$dump_path1" "$dump_path2" "$runtime" "instruction" $flag
	cargo run --package gear-weight-diff --release -- diff "$dump_path1" "$dump_path2" "$runtime" "host-fn" $flag

You can also add a line at the end

+  cargo run --package gear-weight-diff --release -- diff "$dump_path1" "$dump_path2" "$runtime" "memory" $flag
