Make TaskMemory a child class of ProcessMemory

Currently TaskMemory re-implements a number of Read* routines that are
implemented in a platform-independent way in ProcessMemory with access
to a single platform-specific ReadUpTo method. Implement the ReadUpTo
method for TaskMemory and subclass it from ProcessMemory to inherit the
remaining methods.

The ProcessMemoryTests didn't work on macOS because MultiprocessExec
can not access the child process' task port without root privileges or
the task_for_pid entitlement. Create an adaptor class for those tests to
use MachMultiprocess so that the child process sends its task port to
the parent.
