Add make support for Aml_abis and Ndk_abis options
Add a new TARGET_ARCH_SUITE which, when set to 'mainline_sdk' or 'ndk',
sets `Aml_abis: true` in soong.variables.
This is required to enable removing the custom soong.variables that
are being maintained for the ndk and mainline sdk builds.
Bug: 174315599
Test: TARGET_ARCH_SUITE=mainline-sdk m nothing; inspect soong.variables
(ditto for ndk)
