Replace 'use MAPL' with 'use MAPL2' in GEOS_Shared for MAPL→MAPL2→MAPL3 rename

[tclune]

Summary

As part of the MAPL3 rename work (MAPL→MAPL2→MAPL3), all bare use MAPL statements in Fortran source files must be changed to use MAPL2, and CMake DEPENDENCIES lists must include MAPL2 alongside MAPL. This mirrors changes being made in the MAPL repo itself (feature/#4600-rename-MAPL-MAPL2-MAPL3-MAPL).

Changes

• GEOS_Shared/CMakeLists.txt: Add MAPL2 to DEPENDENCIES
• GEOS_Shared/G3_MPI_Util_Mod.F90: use MAPL → use MAPL2
• GEOS_Shared/GEOS_TopoGet.F90: use MAPL → use MAPL2
• GEOS_Shared/OVP.F90: use MAPL → use MAPL2
• GEOS_Shared/atmOceanIntLayer.F90: use MAPL → use MAPL2
• GEOS_Shared/condense.F90: use MAPL → use MAPL2
• GEOS_Shared/surfacelayer.F90: use MAPL → use MAPL2
• GEOS_Shared/tropovars.F90: use MAPL → use MAPL2
• GEOS_Shared/windfix.F90: use MAPL → use MAPL2
