* Fix linking of geos for mingw
Linking stage is failing due to the multiple definitions of the same symbol.
One way of fixing this is to disable inlining for small functions by passing DISABLE_GEOS_INLINE=ON for mingw builds.
* Bump the port version.
* [geos] Bump version

* [GEOS] Generate debug library names with `d` suffix
Currently geos.lib name is used for both, debug and optimised
GEOS libraries. This leads to situation when:
```
find_library(GEOS_LIBRARY_DEBUG NAMES geos)
find_library(GEOS_LIBRARY_RELEASE NAMES geos)
```
finds the same library for both
```
GEOS_LIBRARY_DEBUG=D:/vcpkg/installed/x64-windows/debug/lib/geos.lib
GEOS_LIBRARY_RELEASE=D:/vcpkg/installed/x64-windows/debug/lib/geos.lib
```
This is minimal patch that works around the problem.
Next, complete fix should be submitted to GEOS upstream,
preferably using exported targets.
* [libspatialite] Add missing geos suffixes in static builds
* Bump GEOS version wherever necessary
* Update download package and checksum.
* Replace download from SVN with official release source package.
* Remove generating of geos_svn_revision.h as unnecessary -
released source package includes the header.
* Explain status of the missing CMake modules.
* Remove CMake option -DBUILD_TESTING as unused.
GEOS is important dependency of GDAL (updated in #1879;
GDAL 2.2.2 can still work with GEOS earlier than 3.6.2).
