Add PLATFORM_SYSTEMSDK_VERSIONS and BOARD_SYSTEMSDK_VERSIONS
PLATFORM_SYSTEMSDK_VERSIONS is the list of System SDK versions that the platform is supporting. Contrary to the public SDK where platform essentially supports all previous SDK versions, platform support only a few recent System SDK versions, since some of old System APIs are gradually deprecated, removed from the following SDKs and then finally deleted from the platform. This will be part of the framework manifest. The list can be specified by setting PLATFORM_SYSTEMSDK_MIN_VERSION. If it is set to an old version number, then System SDKs from the version to the current version (PLATFORM_SDK_VERSION) are considered to be supported by the platform. If PLATFORM_SYSTEMSDK_MIN_VERSION is not set, only the latest System SDK version is supported. Next, BOARD_SYSTEMSDK_VERSIONS is the list of System SDK versions that the device is using. This is put to the device compatibility matrix device is using. The device and the platform is considered as compatible only BOARD_SYSTEMSDK_VERSIONS in the device compatibility matrix are in the PLATFORM_SYSTEMSDK_VERSIONS in the framework manifest. When BOARD_SYSTEMSDK_VERSIONS is set, a Java app or library in vendor or odm partitions which didn't specify LOCAL_SDK_VERSION is forced to use System SDK. Also, the build system does the additional integrity check to ensure that LOCAL_SDK_VERSION is within BOARD_SYSTEMSDK_VERSIONS or PLATFORM_SYSTEMSDK_VERSIONS (if BOARD_SYSTEMSDK_VERSIONS isn't set).
