roll: pigweed pw_allocator: Add module config

This adds two new options:

* PW_ALLOCATOR_STRICT_VALIDATION, to allow optionally enabling more
expensive checks that can be used to aggressively enforce invariants
when testing. This option is not used in the current CL, but is used by
subsequent CLs.

* PW_ALLOCATOR_BLOCK_POISON_INTERVAL, to allow setting the poisoning
rate more easily from the build rather than in code via a template
parameter.
