evas font: revise evas_font_init/reinit functions

Summary:
The static flag in evas_font_init() was not useful.
It could be replaced by checking address of "fc_config".
FcInitReinitialize() function was not necessary to reload
configure and font files in Evas. It would be meaningful
when only Evas use Fontconfig's function without own "fc_config".
To reload "fc_config", calling FcInitLoadConfigAndFonts() is enough.
And there is no need to load "fc_config" from evas_font_reinit()
when "fc_config" is not prepared.

Test Plan: N/A
