fix: regression in layouting with fullscreen state and various taskbar alignments

[Dovias]

This PR implements fixes for #790 and #640 issues

I've tested StartAllBack and Windhawk's top taskbar mod by @m417z , but I am pretty confident ExplorerPatcher would also work due to the nature of StartAllBack's use of classic taskbar.

Note: I've learned Rust basics just because how annoying this bug was for me, so if you see some spots which look kind of bad in the code, please review it 🤣

Implementation note: This PR completely removes Rect's apply_delta() and apply_inverse_delta() functions as they were suited only for Window calculations, completely ignoring Workspace delta requirements. All of the calculations required to fix this in this PR were made in-place by constructing a Rect viaRect::from_ltrb() function instead.
