Scudo minimal runtime support for Soong

Browse Source 
Scudo is now compatible with the -fsanitize-minimal-runtime, and offers a new
dynamic library that doesn't bundle UBSan.

This patch adds support for this new library in Soong, preferring it over the
full one, unless a UBSan or diagnostic dependency is found.

Test: aosp compiled with m -j
Test: local test enabling Scudo for tombstoned
