As discussed in the voice chat, let's use git submodule instead.

This is v2 revision of patches that contain the following changes:
- add liburing to the code base
- add macro guard
- fix undeclared GWP_CONN_FLAG_IS_CANCEL macro

My Linux distro didn't have a static version of the liburing library.
Let's just embed the liburing source code directly into the code base.

VS Code's C/C++ linter was complaining about an undefined struct member. 
Adding a macro guard resolved the warning, although I later discovered 
that configuring the defines array in c_cpp_properties.json also fixes 
the issue, but it's still nice to have macro guard as a safe fallback.

And I noticed that declaration of GWP_CONN_FLAG_IS_CANCEL is missing, and
have now declared it.

## Changelog
v1 -> v2:
 - Using git submodule instead of pulling the code base directly.
