Support NOT disabling the ASLR from the debugger

[xusheng6]

Right now, LLDB by default turns off ASLR, which could be an unwanted behavior in certain cases. We can have it turned off by adding " --disable-aslr false" to the launch command . On the other hand, it would not be easy to turn off ASLR in DbgEng (x64dbg does it, but I do not know exactly how; also I am not sure if the technique it uses can be used in DbgEng as well). So chances are that I will have to make this only available for LLDB adapter and not for the DbgEng, at least initailly.

Similar to #563 , but for that one, it is easy to do in DbgEng, but not obvious for LLDB
