Move APP-% and PRODUCT-% implementation out of Kati

This way we'll share ninja files with the equivalent normal configs. We
were already parsing them in the make config step in order to fix
TARGET_PRODUCT / TARGET_BUILD_VARIANT / TARGET_BUILD_APPS, now they
replace themselves in MAKECMDGOALS with the appropriate goals.

If we're not going to pass any goals to ninja, pass the default goal.

Test: ALLOW_MISSING_DEPENDENCIES=true m -j APP-Calculator
Test: m -j PRODUCT-aosp_fugu-eng
Test: m -j PRODUCT-aosp_fugu-eng sdk
Test: m -j PRODUCT-aosp_fugu-sdk
Test: lunch aosp_arm64-userdebug; m -j
Test: lunch aosp_arm64-userdebug; m -j dist
Test: lunch aosp_arm64-userdebug; m -j adb
