The search for height to build track ended at a half-height, leading to (undefined string) error. Changed to always end at whole height and search as high as possible.
* Reduce direct usage of Location_Null
Ideally we want to refactor these out to use std::optional as much as possible but for now move to using the standard interfaces.
* Remove incorrect AND with LOCATION_NULL
In the original this was a simple comparison to check for negative. Unsure how it ended up as an AND with the negative bit.
* Make Map::map_invalidate_element() use CoordsXY
* Make Map::map_invalidate_tile_full() use CoordsXY
* Make Map::map_invalidate_tile_zoom0() use CoordsXY
* Make Map::map_invalidate_tile_zoom1() use CoordsXY
* Make Map::map_invalidate_tile() use CoordsXY
* Use CoordsXYRangedZ for map invalidation
* Fix vehicle tile invalidation use Z instead of Y coord
* Fix BannerRemoveAction sending Z TileCoords to invalidate tile
* Fix wrong tile invalidation on peep_update_walking_break_scenery
* Prefer ToTileStart over bitwise and
* Make Map::map_get_first_element_at() use CoordsXY
* Fix clang-format on ClearAction.hpp
* Prefer TileDIrectionDelta over hardcoded delta on RideConstruction
* Use named Direction constants
* Make Compat::map_get_first_element_at() use CoordsXY
* Use ScreenCoordsXY for windows/Footpath
- Refactor `place_park_entrance_get_map_position()` to receive `ScreenCoordsXY` and return `CoordsXYZD`
- Refactor `sub_68A15E()` to receive `ScreenCoordsXY` and return `CoordsXY`. Some of its usage are narrowing the result on purpose, as same variable is used for contexts where `int16_t` is still a hard requirement.
* Properly increment for big Z and use LOCATION_NULL
* Use ScreenCoordsXY for window_create function
* Use ScreenCoordsXY for window_find_from_point function
* Use ScreenCoordsXY for window_find_widget_from_point
* Use ScreenCoordsXY for ride_contruction_tool*
* Use ScreenCoordsXY for window_event_tool*
* Use ScreenCoordsXY for window_event_scroll_mouse*
* Use ScreenCoordsXY for remaining window_event*
* Use ScreenCoordsXY for window_(set|move)_position
