I04f9e48a1cf9dee915cf51e1e12b17ff0a595a06 provides neutral values for
the Codex tokens in mediawiki.skin.defaults.less in MW core, and expects
skins to import the appropriate Codex themes in their
mediawiki.skin.variables.less.
For both legacy Vector and Vector 2022, import the Codex tokens for the
wikimedia-ui-legacy theme. We need to use the legacy theme because
Vector and Vector 2022 have a base font size of 14px; the non-legacy
theme assumes a base font size of 16px.
Remove some variable assignments that are now redundant, because their
values are the same as the Codex tokens we're importing.
After importing the Codex tokens, override some of their values where
necessary so that all variables' values stay the same(*). We should
consider whether to remove some of these overrides in a follow-up patch,
but keeping everything the same for now makes this change less
disruptive.
(*) As in the core change, one variable's value does change:
- @max-width-breakpoint-tablet from calc(719px) to 719px
but this change has no visual impact.

Follow example in skinStyles and give these their own folders.
The problem with using "legacy" is that it could be interpreted as meaning
legacy LESS variables e.g. deprecated variables.
