generator: Do not generate code for "disabled" extensions

It is unlikely that disabled, reserved extensions (without naming
whatsoever) are used through Ash bindings generated from Vulkan-Headers
releases, and are best ignored to reduce diff noise and spurious issues
[1] with unfinished extension definitions.

This approach matches what is defined in the registry spec for
`supported="disabled"` [2]:

    use `supported="disabled"` to indicate this extension should never
    be processed.
