internal: optimize cursor move a bit (#8264)

* window: inline and const getWindowMainSurfaceBox

getWindowMainSurfaceBox gets called a lot of times from deep down from
mousemoveunified, profiling mousemoveunified it spends quite a lot of
cpu time in here, let the compiler optimize the call to
getWindowMainSurfaceBox by inlining and making it const. reducing the
overhead.

* inputmgr: return early and use std::any_of

return early in mousemoveunified to reduce the amount of unnecessery
calls to various pointers when not needed, also make isconstrained use
std::any_of instead of for loop to use the STL optimized paths with
hopes and dreams marginally faster.

* decoration: return early, reduce temporar copy

return earlier and reduce the temp copies by using one .lock instead of
two
