Add memoization when possible

Some functions are heavily called by Slither, we should add memoization when possible to reduce the execution time. Example:

https://github.com/crytic/crytic-compile/blob/fe6d1ba8bdeacdda31439d60051fba9968e2e8b8/crytic_compile/crytic_compile.py#L231-L245

We could also consider adding a cache to some of the platforms properties, such as:
https://github.com/crytic/crytic-compile/blob/fe6d1ba8bdeacdda31439d60051fba9968e2e8b8/crytic_compile/platform/truffle.py#L268-L276

This requires benchmarking to ensure we improve the performance

We should add a generic way to enable/disable memoization in case the objects are modified by a script

Start by reviewing crytic_compile/crytic_compile.py around lines 231-245 and crytic_compile/platform/truffle.py around lines 268-276. Benchmark the affected functions and platform properties before and after any memoization. Done means measurable execution-time improvement plus a generic way to enable or disable caching when objects may be modified.
