[sanitizer] Allow for the allocator "names" to be set by the tools

Summary:
In the same spirit of SanitizerToolName, allow the Primary & Secondary
allocators to have names that can be set by the tools via PrimaryAllocatorName
and SecondaryAllocatorName.

Additionally, set a non-default name for Scudo.
