Propagate Soong header_libs to module-info.json

Adding the Soong header_libs dependencies to
module-info.json allows tools to more accurately detect
all module-level dependencies. This change adds
LOCAL_HEADER_LIBRARIES, populated from header_libs, to
the Soong's Android.mk prebulit module definition so
that it will propagate through the prebuilt into
base_rules.mk and eventually to module-info.json.

Bug: 151755703
Test: Find header_libs deps in module-info.json
