soong: fix wrong link type for VNDKs

Do not rely on 'module.Name()' to decide VNDK link type.
Some prebuilt modules such as libclang_rt_prebuilt_library_shared and
vndk_prebuilt may have different naming schemes.(prefix/suffix)
And llndk_library module has '.llndk' suffix.

Instead, use VNDK-related properties (e.g. vndk.enabled,
vendor_available, etc.).

Bug: 132800095
Test: m & check LOCAL_SOONG_LINK_TYPE for prebuilts
