Allow GL_RGB9_E5 as a valid fbo format

If GL_QCOM_render_shared_exponent is available then treat
GL_RGB9_E5 as a valid internal format for fbo. Also, allow
copy of RGB9_E5 pixel data.

Components: OpenGL
VK-GL-CTS Issue: 2898

Affects:
KHR-GLES3.packed_pixels.rectangle.rgb9_e5
KHR-GLES3.packed_pixels.pbo_rectangle.rgb9_e5
KHR-GLES3.packed_pixels.varied_rectangle.rgb9_e5
