David Anderson 64b351b882 Add pcluster and deduplication support for erofs images. 
This adds BOARD_xIMAGE_EROFS_PCLUSTER_SIZE and
BOARD_EROFS_PCLUSTER_SIZE, which set the "pcluster size" of erofs images
for individual images or all erofs images respectively. The pcluster
size affects the maximum size of a physical compressed block.

This also adds BOARD_EROFS_SHARE_DUP_BLOCKS, which turns on chunk
support in EROFS.

Bug: 201685920
Test: manual test

Android Make Build System

This is the Makefile-based portion of the Android Build System.

For documentation on how to run a build, see Usage.txt

For a list of behavioral changes useful for Android.mk writers see Changes.md

For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.

This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
