[c++20 module] functions from vk::detail:: pulled into vk::

[qbojj]

vulkan.cppm uses namespace vk { ... using vk::detail::{createResultValue, ignore, resultCheck} ... }, so those symbols are present in the vk:: namespace instead of the original vk::detail::

@sharadhr, could you please have a look on this issue?

Ideally these symbols shouldn't be exported at all, since they're in a detail namespace. It's pretty trivial to remove them, but it's worth testing that the module still works as expected without exporting these synbols.
