refactor(tokens): Update JSON files to support Tokens Studio management

[matgalla]

Related Issue: #11391

Summary

This update makes changes necessary for the modification of Calcite tokens within Tokens Studio. No changes are made to the final tokens themselves in this update.

Criteria for completion:

• Import current token files into TStudio (TStudio automatically moves things around, but there should be no functional change)
• Separate light/dark semantic color tokens into their own files so that TStudio can use them as themes
• Change all instances of "type": "size" to "type": "sizing" For TStudio organization
• Change all instances of "type": "space" to "type": "spacing" For TStudio organization
• Change all instances of "type": "breakpoint" to "type": "dimension" For TStudio organization
• Add TStudio themes for different token types

This update is one step in the process of moving our token management over to Tokens Studio.

Next steps

• Update snapshot tests
• Remove unnecessary token attributes
• Add missing core color tokens
• Fix incorrect core color values
• Audit the structural differences between tokens and Figma variables
• Restructure tokens to align with Figma variables where necessary
• Address Replace inconsistent shadow styles with new shadow tokens #10050
• Address Transparent hover & press tokens #11565
• Address Audit and reconcile bugs and missing colors in Calcite Core Color design tokens #11581
• Address Neutral color primitive value update #11725
• Address [radio-button] Selected states use inner box shadows that aren't supported by existing tokens #11903
• Audit the value differences between tokens and Figma variables (mainly for percentages and typography)
• Finalize token and Figma variable values with Calcite designers and developers
• Update token values to align with Figma variables where necessary
• Document the new token creation and modification process

FWIW, here's the expected test failure before updating the snapshots.

LGTM! I have one code suggestion but it can be done in a follow up if this needs to land ASAP

Suggested change

	const sameValueThemeTokens = light.allTokens
	.filter((token) => isThemed(token))
	.filter((token, index) => token.value === dark.allTokens[index].value);
	const keyToToken = new Map<string, DesignToken>();
	sameValueThemeTokens.forEach((token) => {
	if (token.key) {
	keyToToken.set(token.key, token);
	}
	});
	const keyToToken = new Map<string, DesignToken>();
	light.allTokens.forEach((token, index) => {
	if (isThemed(token) && token.value === dark.allTokens[index].value && token.key) {
	keyToToken.set(token.key, token);
	}
	});

I think this could be simplified, can you confirm?

Nice! I'll add that to #11860.
