Subject: [PATCH] Add api_dirs property and use module name as prefix

The soong connect the prebuilt library according to LOCAL_SDK_VERSION.
But some sdk libraries has diffrent version policy with
LOCAL_SDK_VERSION. For this, we need to support direct link to the
prebuilt library instead of creating a new LOCAL_XXX_SDK_VERSION. So,
The base module name is used as the prefix for the prebuilt module name.

Remove the empty file check to support the absence of a prebuilt
library and add api_dirs property

Bug:77577799
Test: make -j
