Rework TradeQueryGenerator to use exported stat names and values

[vaisest]

Description of the problem being solved:

This PR reworks the QueryMods.lua and weight generation to avoid having to parse mod texts which is not easy and results in extra work, like having to figure out when you need to negate mod values, etc.

Instead, this exports stat names and values for mods:

["BodyArmourImplicitIncreasedLife1"] = {
	"+(60-80) to maximum Life",
	["affix"] = "",
	["group"] = "IncreasedLife",
	["level"] = 1,
	["modTags"] = {
		"resource",
		"life",
	},
	["statOrder"] = {
		887,
	},
	["tradeHashes"] = {
		[3299347043] = {
			["canonicalStat"] = "base_maximum_life",
			["statValues"] = {
				["base_maximum_life"] = {
					["max"] = 80,
					["min"] = 60,
				},
			},
		},
	},
	["weightKey"] = {
	},
	["weightVal"] = {
	},
},

Implicit mod IDs are also exported for item bases.

These can be used to easily generate a modline later with data.describeStats(), while being able to plug the stat value directly into the trade site. This, in my opinion, makes the code a lot more readable and simpler. The existing code also works around some exceptions, like "an additional" being converted to 1 additional. Issues like these are completely avoided

This is based on #2347.

This PR shouldn't have many functional changes, but this does fix the roll ranges for # to # flat damage mods. Previously, e.g. 1 to 300 lightning damage would be tested as 150 to 150 lightning damage, which might not be realistic.
