Split PRODUCT_USE_LOGICAL_PARTITIONS into sub-flags.

Split the flag into PRODUCT_USE_DYNAMIC_PARTITION_SIZE
and PRODUCT_BUILD_SUPER_PARTITION. More sub-flags can be
added with the same way.

Also change some checks with USE_LOGICAL_PARTITIONS with
the appropriate sub-flags.

This allows easier device bring-up to fulfill the requirements
separately.

This also enables dynamic partition size without logical patition.
Originally, to enable BOARD_*_PARTITION_RESERVED_SIZE must also
enable PRODUCT_USE_LOGICAL_PARTITIONS. The patch fix the rule to
let dynamic partition size is able to be used independently.

Fixes: 111966003

Test: make superimage with PRODUCT_USE_LOGICAL_PARTITIONS

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For an outdated reference on Android.mk files, see build-system.html.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.
