macOS: Rename OSX_*_VERSION properties to MACHO_*_VERSION
The properties added by commit 4a62e3d97c (macOS: Add OSX_COMPATIBILITY_VERSION and OSX_CURRENT_VERSION properties, 2020-01-24, v3.17.0-rc1~80^2~1) are general-purpose for all platforms using Mach-O formats and not just on OS X. Rename them accordingly. The properties are new to the CMake 3.17 release so we can rename them without compatibility concerns. Fixes: #20442

+MACHO_CURRENT_VERSION
+---------------------
+
+What current version number is this target for Mach-O binaries.
+
+For shared libraries on Mach-O systems (e.g. macOS, iOS)
+the :prop_tgt:`MACHO_COMPATIBILITY_VERSION` property correspond to
+``compatibility version`` and ``MACHO_CURRENT_VERSION`` to ``current version``.
+See the :prop_tgt:`FRAMEWORK` target property for an example.
+
+Versions of Mach-O binaries may be checked with the ``otool -L <binary>``
+command. If ``MACHO_CURRENT_VERSION`` is not set, the value of
+the :prop_tgt:`VERSION` property will be used.
