Remove vendored usvfs and Windows-only usvfs code paths

The Linux port uses its own in-process FUSE VFS (FuseConnector), so
usvfs was dead weight: libs/usvfs/ was never built, usvfsconnector.cpp
was explicitly REMOVE_ITEM'd from the source list, and every call site
was already guarded by #ifdef _WIN32 with a working Linux branch (the
Windows build is also broken on this branch, since FUSE3 is a hard
find_package dependency).

- Drop libs/usvfs/ and src/src/usvfsconnector.{cpp,h}
- Collapse #ifdef _WIN32 / usvfs include branches in organizercore,
  mainwindow, settings, util, spawn
- Remove getUsvfsVersionString() and the "usvfs: ..." log field
- Remove vfs32/64DLLName APPPARAMs (nothing reads them)
- Relabel About dialog "usvfs:" row to "VFS: FUSE 3"

- * @brief inject a dll into the target process
- * @param processHandle handle of the process to inject to
- * @param threadHandle handle of the main thread in the process
- * @param dllname name/path of the dll to inject. The path can't be longer than MAX_PATH
- * characters
- * @param initFunction name of the initialization function. Can't be longer than 20
- * characters. If this is null, no function is called. Important: the init function has
- * to exist, be exported, take the two userdata parameters and must be __cdecl calling
- * convention on 32bit windows! Failing any of these the target process will crash or
- * the dll isn't loaded Why __cdecl? Because otherwise we would need .def files to
- * export the init function with a GetProcAddress-able function name.
- * @param userData data passed to the init function
- * @param userDataSize size of the data to be passed
- * @param skipInit skip the call to the init function if the named function wasn't found
- * in the dll. If false, the target process will crash if the function isn't exported in
- * the dll
