Add a different implementation of insmod.sh

Use soong namespace to branch a implementation of insmod.sh .
The newly added implementation is only added to PRODUCT_PACKAGE
for dev option enabled devices. The only change to the script is
skip loading kernel modules from vendor|system_dlkm when under 16K
mode.

Test: Dev option works
Bug: 319335586
