feat: write the romset table from the profiles

The FAQ table of arcade romsets was typed by hand and told readers to
collect MAME 0.160 and FinalBurn Neo 1.0.0.2 sets for cores whose source
states 0.159 and 1.0.0.03. generate_site now writes it between generated
markers from the profiles, and a test holds the page to the generator.
An emulator page names where its version is read (the file, the tag and
the commits after it, the package), and says when the code states none
or the version could not be confirmed. HBMAME no longer claims a MAME
romset. tools.md and profiling.md document version_basis and the two
modes.
