Christopher Ferris fc26d71af1 Create a lib that uses scudo instead of jemalloc.
The media processes already use scudo as their allocator. However, it
doesn't really correctly replace the normal allocation functions, so create
a set of wrappers that allow us to use scudo closer to how jemalloc is used.

This is only a temporary change, and should be removed for the next
release of Android. In that version, we will be using standalone
scudo which won't require this wrapper code.

Bug: 123689570

Test: Ran new bionic unit tests. There are failures, but only with
Test: extensions that scudo does not support.
