PSA: test operations with small buffers #7541

Estimated task size: large (2w+)
In the PSA tests, we aren't systematically testing behavior when an output buffer is too small.
When an output buffer is too small:
PSA_ERROR_BUFFER_TOO_SMALL
(at least if no other error condition applies).length
output parameter must be set to a value that's smaller than the size.(Re-raised from a private tracker from the early days of the PSA code.)
Size estimate: between M and L. I'm filing as L because this is definitely not a single-PR task. There's not much of a design space but quite a bit of code to write.
