Update PQparameterStatus and ParameterStatus docs
Cover scram_iterations, which was added in commit
b577743000cd. While
at it, turn the list into a <simplelist> with 2 columns, which is much
nicer to read.
In master, remove mentions of antediluvian versions before which some
parameters were not reported.
Noticed while investigating a question by Maiquel Grassi.
Backpatch to 16.
