Fix Windows ANGLE Workaround Regression of commit 923d9dd7f1d40db72d35ca76a761ca14babf147f

We are aware that Google's ANGLE (Windows EGL/ES2 impl. based on D3D)
crashes using eglInitialize(..) w/ EGL_DEFAULT_DISPLAY.

Commit 923d9dd7f1d40db72d35ca76a761ca14babf147f moved the EGL device initialization
into the EGLDrawableFactory ctor and hence slipped out ANGLE workaround to disable it per default.

- Moving property static flags from GLProfile -> GLDrawableFactory
- Moving ANGLE workaround right into EGLDrawableFactory (where it belongs)
- Moving optional EGL/ES disable code to GLDrawableFactory (where it belongs)

Tested on Windows w/ Java-32bit and latest Chrome ANGLE DLLs
