RTEMS | Refactor the first-fit heap implementation for modular allocator support (#5620)

[Sebastian Huber (@sebhub)]

I am interested to get the first-fit heap allocator replaced with a Two-Level Segregated Fit allocator. Is there a project overview available?

Allocators usually don't implement the boundary condition. I added this some time ago for the libbsd, however, in hindsight this was a mistake. I would remove this feature from the first-fit heap implementation. The boundary allocation can fall back to an alignment of `MAX(alignment, boundary)`.
