Fix EGLConfig for shared video platform surface
[Title] Fix EGLConfig for shared video platform surface
[Issue#] https://bugs.tizen.org/jira/browse/TIVI-436
[Problem] EGLConfig fails on MESA egl
[Cause] Strict EGLConfig isn't necessary for video Pixmap surface
[Solution] drop unnecessary EGLConfig:
remove EGL_MATCH_FORMAT_KHR/EGL_FORMAT_RGBA_8888_EXACT_KHR
MESA egl doesn't implement EGL_MATCH_FORMAT_KHR feature.
Anyway, I don't think it's important for video case;
because Pixmap is native content, its format depends on
gfx driver and matches with gfx driver.
remove EGL_SURFACE_TYPE/EGL_LOCK_SURFACE_BIT_KHR
EGL_LOCK_SURFACE_BIT_KHR is not necessary.
since video has dedicate graphics layer, there is no
CPU operation on it in hw accelerated video path
