Data: Separate data & css/effects camelCase implementations

The camelCase implementation used by the data module no longer turns `-ms-foo`
into `msFoo` but to `MsFoo` now. This is because `data` is supposed to be
a generic utility not specifically bound to CSS use cases.

Fixes gh-3355
Closes gh-4365
