Optimize setting the font when drawing in RenderTextLinux.

Optimize setting the font when drawing in RenderTextLinux.

Avoid creating a temporary |gfx::Font| just to get its
name and size to pass it to Skia.

Note: There's room for further optimizations here, such
as caching, which I plan to look at in a future CL.

BUG=107394
TEST=Run aura and check that omnibox still looks fine. Run about:tracing and check that time used by this code is significantly decreased.
