Add script to automatically minimize pragma

[Amxx]

Follow up to #5730, Replaces #5649

This adds a scripts that finds the minimal pragma that can be used for a given file.

Usage:

npm run pragma # minimize pragma for all solidity files in contracts/ (mocks excluded)
npm run pragma -- -p 'contracts/accounts/**/*.sol' # minimize pragma for a given subfolder
npm run pragma -- -p 'contracts/utils/Address.sol' # minimize pragma for a given file

Running this script is slow, and should probably not be run in CI. It should be a maintenance operation run every now and then. The pragma validity check (yarn test:pragma) already verifies that the pragma are valid.

Why are we updating mocks? Aren't they skipped by default?

Why are we updating mocks? Aren't they skipped by default?

They are, but just for fun I did run the script on the mocks, and it found two things.

I said "why not" update that ... but if you prefer we can dismiss that.

The thing is, mocks include mocks/docs ... and maybe these should be processed.
