[RFC PATCH 5/9] ui/gtk: Factor out tab window creation into a separate function

[Dongwon Kim]

From: Vivek Kasireddy <vivek.kasireddy@intel.com>

Pull the code that creates a new window associated with a notebook
tab into a separate function. This new function can be useful not
just when user wants to detach a tab but also in the future when
a new window creation is needed in other scenarios.
