Copy missing globals from builtin to es*

[silverwind]

While investigating why eslint wouldn't pick up the BigInt globals, I noticed eslint does not use builtin like I previously assumed. I'd like to propose to copy any globals missing in either es5, es2015, es2017 but present in builtin to one of those respective environments.

Afterwards, I'd copy back any potential globals from the es* categories to builtin so that it ends up containing all globals from those categories. Alternatively, builtincould be generated dynamically in index.js, I think actually, that'd be my preference to avoid future inconsistency.

Alternatively, we could also drop builtin which serves no clear purpose in my eyes. Nowadays, es5 should be considered as the baseline.

If anyone wants to work on this, see the initial attempt and feedback in #158.

This already fixed, tests

globals/test.mjs

Lines 62 to 88 in d4082e2

	test('es versions', t => {
	const builtins = new Map(Object.entries(globals.builtin));
	const esVersions = ['es5', ...Array.from({length: 2024 - 2015 + 1}, (_, index) => `es${2015 + index}`)];
	let previousVersion;
	for (const esVersion of esVersions) {
	const data = globals[esVersion];
	for (const [key, value] of Object.entries(data)) {
	t.true(builtins.has(key), `The builtin '${key}' in '${esVersion}' is missing in 'builtin'.`);
	t.is(value, builtins.get(key), `Value of '${key}' should be the same as 'builtin'.`);
	}
	if (previousVersion) {
	t.deepEqual(
	previousVersion.globals.filter(key => !Object.hasOwn(data, key)),
	[],
	`The builtins in '${previousVersion.esVersion}' are missing in '${esVersion}'.`,
	);
	}
	previousVersion = {esVersion, globals: Object.keys(globals[esVersion])};
	}
	const latestVersion = esVersions.at(-1);
	t.deepEqual(globals[latestVersion], globals.builtin, `'${latestVersion}' should be the same as 'builtin'.`);
	});

About dripping "builtin", see #158 (comment) add #252 (comment), let's keep it.

But do you think we should name it as "es-latest"?
