Don't use old VNDK and SystemSDK versions for new devices

We need to prevent vendors from using old VNDK and SystemSDK versions
for newly launched device. Otherwise, deprecating old versions of the
APIs would be really difficult.

Specifically, it is enforced that

PRODUCT_SHIPPING_API_LEVEL <= BOARD_VNDK_VERSION

PRODUCT_SHIPPING_API_LEVEL <= min(BOARD_SYSTEMSDK_VERSIONS)

Bug: 72126206
Test: manually setting BOARD_VNDK_VERSION to 24 in
device/google/wahoo/BoardConfig.mk and choosecom to walleye
Test: m -j shows an error on BOARD_VNDK_VERSION
Test: BOARD_SYSTEMSDK_VERSION="25 26" m -j shows an error on
BOARD_SYSTEMSDK_VERSION
