handle CMC GC strategy

[matbrik]

Fixes #323
It is related to this commit liuyufei@c52014e which was made to force an update of the ArtMethods containing the hooks after a GC.

With the recent updates of Android/libart/Google Play System Updates on certain devices it has been enabled the CMC (MarkCompact collector) instead of CC (ConcurrentCopying).

Still the app is dying on Google Pixel 6 Pro + Android 14 (AP2A.240705.004, 2024.07) + KernelSU 1.0.0 (LKM Mode) + Frida 16.4.7.

When I checked the logcat, the app is dying after Using CollectorTypeCMC GC.

Is there any way?

Enable userfaultfd-based CMC GC by default on Android S(13) and above.

Before this change, the Concurrent Mark-Compact Garbage Collector
(CMC GC) was enabled by default (provided the kernel supports
userfaultfd) on Android T(14) and above. Extend this behavior to
Android S(13) and above.

This reverts commit a9102c122084ced4a5369d2c2174ea1b83b4e1c9.
