[inspector] Add test for getPossibleBreakpoints on embedded code

This tests calling Debugger.getPossibleBreakpoints on a user function
embedded into the startup snapshot.

Currently, this fails because inspector does not know how to handle
scripts without an associated context. The test should be updated
once we have a fix.
