Add Pbuffer support on Tizen platform

Merged old commit:
commit f409ef598976a4fd4f74ab4695478b1fc1651c06
Author: Zhaowei Yuan <zhaowei.yuan@samsung.com>
    1. Add EGL_PBUFFER_BIT to surface_type if maskes match
    2. Alloc local buffer when render buffer type is
    "FRONT_LEFT" which will be used by Pbuffer

commit b0dec10d0d0fbc7f77623016f3d986122f718f8b
Author: Xuelian Bai <xuelian.bai@samsung.com>
    Fix crash when query a pbuffer surface
    Pbuffer is not created via TPL, so when query a pbuffer surface,
    we can only call _eglQuerySurface instead of TPL APIs.
