Mesa: Add support for GL_OES_texture_*float* extensions.

This patch series adds support for following GLES2 Texture Float extensions: 1)GL_OES_texture_float, 2)GL_OES_texture_half_float, 3)GL_OES_texture_float_linear, 4)GL_OES_texture_half_float_linear.

Gallium drivers just need to enable the extensions now.
