PR #20058: Size comparison from 41e474d to 805a28a Increases (17 builds for cc13x2_26x2, linux, nrfconnect, telink)
Decreases (15 builds for cc13x2_26x2, cyw30739, efr32, linux, nrfconnect)
Full report (39 builds for cc13x2_26x2, cyw30739, efr32, k32w, linux, mbed, nrfconnect, p6, telink)

There were only two consumers (the retrans table and exchanges) left, which both used to fail unit tests if using ObjectPool due to use-after-free. One of those tests is now fixed; the other is fixed in this PR. So we can move to using ObjectPool everywhere. Fixes project-chip#14509 Fixes project-chip#14446

There were only two consumers (the retrans table and exchanges) left, which both
used to fail unit tests if using ObjectPool due to use-after-free.
One of those tests is now fixed; the other is fixed in this PR. So we can move
to using ObjectPool everywhere.
Fixes #14509
Fixes #14446
Problem
We have use-after-free that is being covered up by using pool allocation.
Change overview
Fix the use-after-free in WriteHandler, switch to ObjectPool for the last BitMapObjectPool holdouts.
Testing
Should pass CI.
