psql: Add option to use expanded mode to all list commands.

This allows "x" to be appended to any psql list-like meta-command,
forcing its output to be displayed in expanded mode. This improves
readability in cases where the output is very wide. For example,
"\dfx+" (or equivalently "\df+x") will produce a list of functions,
with additional details, in expanded mode.

This works with all \d* meta-commands, plus \l, \z, and \lo_list, with
the one exception that the expanded mode option "x" cannot be appended
to "\d" by itself, since "\dx" already means something else.
