Introduce enableLegacyPatching flag for CSS patching
As part of the dark mode migration we are adding
`enableLegacyPatching:true` to all call sites of `appendStyle` (and
related methods). If a user passes `false` for that flag, no CSS colour
patching will occur.
This CL is therefore a no-op from a user's perspective as we pass `true`
on every call to maintain existing behaviour, but once we start
migrating we will turn the option to `false`. Long term, once all code
is migrated and the old patching is removed, we will remove this flag
entirely once again.
