Move "Method Hooking" to separate technique

This technique currently contains a very specific example of hooking, rather than the generic technique. On the other hand, the tool page for Frida on Android (https://mas.owasp.org/MASTG/tools/android/MASTG-TOOL-0001/) explains how to actually hook methods using Frida and not go too deep. Just explain how to create a hook and how to run it.

MASTG-TECH-0043 should probably explain how to simply hook using different frameworks (e.g. LSPOSED and Frida) and a separate page (technique?) can be made for applying that technique to solve a crackme.
