tcg: convert "-accel threads" to a QOM property

Replace the ad-hoc qemu_tcg_configure with generic code invoking QOM
property getters and setters.  More properties (and thus more valid
-accel suboptions) will be added in the next patches, which will move
accelerator-related "-machine" options to accelerators.
