Update hardcoded sets of Formats utils to be computed programmatically from PS data

[scheibo]

Similar to #5 and #6, there exist several outdated hardcoded tables in utils.ts:

stats/stats/src/util.ts

Lines 110 to 139 in 50b3c1b

	const NON_SINGLES_FORMATS = new Set([
	'battlespotdoubles', 'battlespotspecial7', 'battlespottriples', 'doublesou', 'doublesubers',

These should be updated for legacy mode purposes and then methods like isNonSinglesFormats etc should really just use on information present in the Dex otherwise.

[scheibo]

One actual issue here with programmatically computing formats is that the formats included in the @pkmn/dex package differ from upstream (@pkmn/dex does not include OMoTM formats, for instance), though that shouldn't matter for the formats at play here. The bigger challenge is that many legacy formats get pruned from PS/pkmn, so data on formats like 'orassmogondoubles' no longer exist and may need to remain hardcoded
