message_arena: Use forward_list instead of list

I was looking at CPU profiles to understand shared library
microbenchmarks and I found this simple optimization.

This seems to have a small positive impact on microbenchmarks.

It also has a small positive impact on code size. sdk_example before was
22133864 bytes (1013912 bytes when stripped). Now it is 22024792 bytes
(1005496 when stripped).
