contracts: What's with the solc optimizer settings?

[matevz]

SUMMARY

Followup to https://github.com/oasisprotocol/sapphire-paratime/pull/477/files#r1896639760

It seems this solc optimizer snippet is required for any example that uses sapphire-contracts:

sapphire-paratime/contracts/hardhat.config.ts

Lines 47 to 56 in 6acf367

	solidity: {
	version: '0.8.20',
	settings: {
	optimizer: {
	enabled: true,
	runs: (1 << 32) - 1,
	},
	viaIR: true,
	},
	},

Investigate, why the optimizer setting is there in the first place. Execution speed? Security? Blame says these lines are 3 years old. Then figure out why this snippet is not required by external projects that import sapphire-contracts npm package.
