Fixes gde library copying

[dmitrii-t]

Fixes the following scons error

scons: *** Multiple ways to build the same target were specified for: bin\windows\extension.windows.template_debug.x86_64.dll (from ['src\register_types.windows.template_debug.x86_64.obj'] and from [])

Adds projectlib as a target and modifies the command to copy extenxion library to from .\bin to the projeect's .\demo\bin\

I'm not sure why the current code uses env.Command and shutil. This should be done via env.InstallAs instead:

@dmitrii-t If you could change your PR to match @Faless' suggestion, we will merge it.

@Faless I didn't even know that it existed! Thanks for the tip.

Hey @dmitrii-t not sure if you are done with the PR but could you squish the commits if if it is ready?
