rename jtag_khz as adapter_khz

Globally rename "jtag_khz" as "adapter_khz", and move it out of the "jtag"
command group ...  it needs to be used with non-JTAG transports

Includes a migration aid (in jtag/startup.tcl) so that old user scripts
won't break.  That aid should Sunset in about a year.  (We may want to
update it to include a nag message too.)
