CYAZ elevation fixes and small scenery enhancement

This add-on fixes some elevation issues with CFSS Long Beach/Tofino (CYAZ), fixing the "mushroom rocks" and hole between runways in recent World Updates and MSFS 2024. It's compatible with the Pacific Rim Coastline & Tree Enhancements add-on (https://flightsim.to/file/26405/pacific-rim-coastline-tree-enhancements). It also enhances the Long Beach parking lot seen on approach.
