Patch to add small caps to font cache


When rendering with FAST_PATH turned off, the complex path for small caps data directly requests a FontPlatformData with SmallCapsVariant. Currently the SmallCapsVariant and the PlainVariant will have the same hash and occupy same space in the font cache resulting in incorrect rendering (always Small Caps or always plain)

Steps to Reproduce:

1) Build with fast path disabled
2) Load a webpage using small caps of a particular font
3) Load another page with exactly the same font but without small caps

Expected Results:

The small caps page will have small caps, the plain page will have plain.

Actual Results:

Both pages have Small Caps (likewise if steps 2 and 3 are reversed both pages will have plain).
