GPU Memory: add sepolicy rules around bpf for gpuservice
1. Allow gpuservice to access tracepoint id
2. Allow gpuservice to access bpf program
3. Allow gpuservice to attach bpf program to tracepoint
4. Allow gpuservice to access bpf filesystem
5. Allow gpuservice to run bpf program and read map through bpfloader
6. Allow gpuservice to check a property to ensure bpf program loaded
Bug: 136023082
Test: adb shell dumpsys gpu --gpumem
