Make libperfetto_client_experimental available to product and APEX

This change makes the Prefetto SDK library available to more vendor
code. Since it already was vendor_available, it does not change *who*
can use it, but provides more options for placement of binaries.

Test: made and built a product_specific sample that emits track events
