We were hardcoding kMaxAppMessageLen and kMaxSecureSduLengthBytes, but those defines were not even consistent with each other, and both were overly conservative. Specific changes:

  1. Fix computation of CHIP_SYSTEM_HEADER_RESERVE_SIZE: we don't have any "crypto headers".
  2. Fix computation of kMaxAppMessageLen to use our actual packet buffer sizes and defined header sizes.
  3. Fix kMaxSecureSduLengthBytes to be consistent with kMaxAppMessageLen.

@bzbarsky-apple
Improve size calculation for our packets.
eb00a31 
We were hardcoding kMaxAppMessageLen and kMaxSecureSduLengthBytes, but those
defines were not even consistent with each other, and both were overly
conservative.  Specific changes:

1. Fix computation of CHIP_SYSTEM_HEADER_RESERVE_SIZE: we don't have any "crypto
   headers".
2. Fix computation of kMaxAppMessageLen to use our actual packet buffer sizes
   and defined header sizes.
3. Fix kMaxSecureSduLengthBytes to be consistent with kMaxAppMessageLen.

Improve size calculation for our packets. (project-chip#28563)
c275f21 
* Improve size calculation for our packets.

We were hardcoding kMaxAppMessageLen and kMaxSecureSduLengthBytes, but those
defines were not even consistent with each other, and both were overly
conservative.  Specific changes:

1. Fix computation of CHIP_SYSTEM_HEADER_RESERVE_SIZE: we don't have any "crypto
   headers".
2. Fix computation of kMaxAppMessageLen to use our actual packet buffer sizes
   and defined header sizes.
3. Fix kMaxSecureSduLengthBytes to be consistent with kMaxAppMessageLen.

* Simplify the size computation logic.
