Remove handling of deprecated TRIM_MEMORY levels in VirtualMachine

This CL removes handling of several deprecated `TRIM_MEMORY` levels in
the `VirtualMachine` class.  The removed levels include
`TRIM_MEMORY_RUNNING_CRITICAL`, `TRIM_MEMORY_RUNNING_LOW`,
`TRIM_MEMORY_RUNNING_MODERATE`, and `TRIM_MEMORY_COMPLETE`.

The level < TRIM_MEMORY_UI_HIDDEN is now target on 10% memory release.
The level that TRIM_UI_HIDDEN <= level < TRIM_MEMORY_BACKGROUND targets
on 30% memory release. The level >= TRIM_MEMORY_BACKGROUND targets on
50% memory release.

Android Virtualization Framework (AVF)

Android Virtualization Framework (AVF) provides secure and private execution environments for executing code. AVF is ideal for security-oriented use cases that require stronger isolation assurances over those offered by Android’s app sandbox.

Visit our public doc site to learn more about what AVF is, what it is for, and how it is structured. This repository contains source code for userspace components of AVF.

If you want a quick start, see the getting started guideline and follow the steps there.
