SCons: Keep exceptions and rtti on Android, iOS and HTML5 tools build 

Those were disable to keep size small, and on Android avoid the dependency on the STL,
but for tools build (editor) this is not really a concern.

Note: as of today it's not possible to build tools=yes for those platforms, but this
change is one of the necessary steps to enable it.

Fixes #25262.
