Add a show function for "maint show worker-threads"
I wanted to see how many threads gdb thought it was using, but
"maint show worker-threads" only reported "unlimited". This patch
adds a show function so that it will now report the number of threads
gdb has started.
Regression tested on x86-64 Fedora 34.
