With the recent Linux rewrite, I attempted to simplify the number of
wrapper structs involved in the Linux code, following the macOS code as
an example. Unfortunately, I missed a vital component: pointers to the
platform state, held by platform data structures. As we hold all of the
platform data structures on Linux, this PR reintroduces a wrapper around
the internal state of both the platform and the window. This allows us
to close and drop windows correctly.
This PR also fixes a performance problem introduced by:
https://github.com/zed-industries/zed/pull/10343, where each configure
request would add a new frame callback quickly saturating the main
thread and slowing everything down.
