Extending the font variant to text

[thibaudbrault]

Currently the font variant property can only be used for numbers but, in CSS, it can be used for texts to change the ligature with font-variant-ligatures or to control the use of alternate glyphs with font-variant-caps.

The current properties for font-variant-caps do not have an equivalent in Tailwind so they could be used as class:

small-caps
all-small-caps
petite-caps
all-petite-caps
unicase
titling-caps

A -caps could be added to unicase

This is the same for the properties of font-variant-ligatures:

common-ligatures
no-common-ligatures
discretionary-ligatures
no-discretionary-ligatures
historical-ligatures
no-historical-ligatures
contextual
no-contextual

A -ligatures could be added for the last two values.
