Support for --start-group / --end-group when linking native extensions

**Is your feature request related to a problem? Please describe :**
When building a native extension, the order that the required libraries are supplied to the linker can't be controlled, and in particular dependencies can be listed before the library built from the NE source.
See forum post [here](https://forum.defold.com/t/ne-library-link-order/72814)

**Describe the solution you'd like :**
Extender wraps the libraries in --start-group / --end-group

**Describe alternatives you've considered :**
None I can think of.

**Additional context :**
[This branch](https://github.com/DreamRealityInteractive/extension-firebase/tree/desktop) of extension-firebase can be used to reproduce the problem when building a x86_64-win32 target.
