In order to generate R.java of app modules, AIDEGen needs to build
the module. It might cause system.img oversized so we turn to build
the target srcjar file if it exists in module-info.json.
Build module-info.json without this change:
Build time: 1m47.227s
File size: 14,186,429 Bytes
Build module-info.json with this change:
Build time: 1m46.796s
File size: 14,614,470 Bytes
Bug: 132407603
Test: 1. m out/target/product/generic_x86_64/module-info.json
2. by grep "target/common/obj/APPS/Settings_intermediates/aapt2.srcjar"
in module-info.json.

os_version is important for keymaster version binding, where it
refuses to perform operations with a key that is bound to an old
system version. This ensures that an attacker who discovers a
weakness in an old version of system or TEE software cannot roll a
device back to the vulnerable version and use keys created with the
newer version.
Previously, os_version for system.img is added into boot.img header
for bootloader to read the value then pass to TEE before booting the
HLOS. However, with project Treble to modularize each partition, all
images are now in the trajectory to be built independently (still
on-going). Also, in the Generic System Image (GSI) compliance test,
the os_version in OEM's boot.img cannot reflect the actual version of
GSI.
This CL adds per-partition os_versions into AVB metadata, which is
readable by bootloader via libavb without file system dependency. It's
still unclear for how os_version in non-system partition should be used.
We just add them for completeness here.

(cherry picked from commit 9b54801b58)
As a PRODUCT variable, PRODUCT_EXTRA_VNDK_VERSIONS is not allowed to
be assigned from the build command. Instead, we can use
OVERRIDE_PRODUCT_EXTRA_VNDK_VERSIONS in the build command to
override PRODUCT_EXTRA_VNDK_VERSIONS.
