[roll third_party/pigweed] pw_allocator: Add MultiplexAllocator

This CL adds an allocator-like type that can multiplex between several
sub-allocators. If differs from the `Allocator` API in that each method
takes an additional token as a parameter.

These tokens are used to identify groups of memory requests and are
application-specific. This class facilitates mapping those tokens to
platform-specific allocators. This allows applications to use more
platform-agnostic dynamic memory, in turning allowing application reuse
across mutliple platforms, e.g. several generations of a product.
