[3.0] Improve handling of Khronos enum native names (#2534)

* Fix incorrect GLEnum native name (and similar); Fix non-ideal native name for certain Vulkan enums

* Edit comment

* Use uint as the base type for GL-style enums instead of GLenum

* Use GLenum/ALenum/ALCenum has the base type and specify C# type in typemap

* Improve handling of OpenGL-style bitmask enums

* Replace primary constructor of EnumGroup with explicit properties

* Fix my incorrect handling of WGL/GLX namespaces

* Use cl_bitfield for backing type of OpenCL enums
