vim-patch:9.1.0610: filetype: OpenGL Shading Language files are not detected (#29831)

Problem:  filetype: OpenGL Shading Language files are not detected
Solution: detect various file extensions as GLSL filetype, include
          indent and syntax script, do no longer recognize '*.comp'
          as Mason filetype (Gregory Anders)
