Fix version check macros

Browse Source 
These were defined backwards to the usual convention.

 #if GLSLANG_VERSION_GREATER_THAN(11, 10, 0)

This reads as "if glslang version is greater than 11.10.0" to any
reasonable sane programmer, and should therefore expand to
"glslang_version > macro_argument".

Yet the check it references was actually written as "macro_argument >
glslang_version", thus expressing the completely opposite condition of
"if glslang version is *less than* 11.10.0". This is definitely
backwards and extremely, dangerously surprising behavior to any
programmer familiar with such version macros.

I'm not sure if anybody actually ever used them. I certainly didn't, on
account of them being backwards. I could not find a single reference to
them on GitHub (other than in copies of this header) - every project I
found just used the GLSLANG_VERSION_MAJOR etc. macros directly.
