Adding renderdoc capture feature for android

This feature is to add a frame delimiter for OpenGL to enable Renderdoc capturing certain frame without capturing every single frame on android platform. You can use RenderDoc UI to capture OpenGL. For Vulkan RenderDoc capture, since it doesn't have access to VkCommandBuffer which is needed to mark as a frame delimiter on RenderDoc, instead it's creating dump file on android storage and uses the size of dump file as a number of frames to capture. The script is to create and delete dump file and will work for both GL and Vulkan.

This is the script file to trigger capture for Vulkan capture.sh
