Docs: Replace blockdiag/seqdiag with Mermaid

Replace the abandoned sphinxcontrib-blockdiag and sphinxcontrib-seqdiag
Sphinx extensions with sphinxcontrib-mermaid in docs configuration.

None of the documentation in this repository uses blockdiag or seqdiag
directives; this is a config-only cleanup.
