Wrong enum definition
```nim
VkColorComponentFlagBits {.size: 4.} = enum
  VK_COLOR_COMPONENT_R_BIT = 1, VK_COLOR_COMPONENT_B_BIT = 2,
  VK_COLOR_COMPONENT_A_BIT = 4
```
missing `VK_COLOR_COMPONENT_G_BIT`
https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VkColorComponentFlagBits.html
since its generated, i assume that other enum definitions might be broken too
