Reland "Pin FcConfig for FCIDirect at creation."

This reverts commit d7f7cc87910800232c5900ebb64c0c00781cd0c2.

SkFontConfigInterfaceDirect class methods used the FontConfig library
static global "current" FcConfig (implicitly through the use of
nullptr). This was pinned down once per call to each method which used
it (to avoid the "current" FcConfig from being changed out from under it
while running). However, the use of global state as a matter of course
makes it very difficult to reliably test.

Modify SkFontConfigInterface to optionally take an FcConfig on
contruction. If nullptr is provided it is equivelent to the old behavior
so that existing users are unaffected. SkFontConfigInterface takes
ownership of any passed FcConfig and will release it on destruction.
