The DynFile::read_to_end, DynFilesystem::read and
DynFilesystem::read_chunk methods use a heapless::Vec to store a

abstracts over different versions of heapless so that we can optionally
support multiple heapless versions at the same time.

very small overhead. To decrease complexity, this patch removes the
feature and always enables the previously feature-gated code.

by littlefs2, but without a specific implementation.
