Reduce CAmkES per-component heap allocation.
Reduce CAmkES per-component heap allocation.

Set the per-component static heap size to 8KB. The heap is only used by
CAmkES RPC for marhsaling dynamic array & string parameters. We mostly
use the former and no more than 4KB at a time so 8KB should be fine until
we can redirect C use to the Rust heap allocator (or replace the C code).
