[PATCH] wined3d: Check GLSL version when using ARB_shader_bit_encoding with uvec4.

[Paul Gofman]

Wine-Bug: https://bugs.winehq.org/show_bug.cgi?id=47039

There are GPUs which support ARB_shader_bit_encoding with GLSL
version 1.2 and uvec4 data type is available since GLSL 1.3.
Spotted with Intel Ironlake Mobile.
