qemu-options: rewrite help for -smp options

The -smp option help is peculiarly specific about mentioning the CPU
upper limits, but these are wrong. The "PC" target has varying max
CPU counts depending on the machine type picked. Notes about guest
OS limits are inappropriate for QEMU docs. There are way too many
machine types for it to be practical to mention actual limits, and
some limits are even modified by downstream distribtions. Thus it
is better to remove the specific limits entirely.

The CPU topology reporting is also not neccessarily specific to the
PC platform and descriptions around the rules of usage are somewhat
terse. Expand this information with some examples to show effects
of defaulting.
