thread-pool: avoid per-thread-pool EventNotifier
EventNotifier is implemented using an eventfd or pipe. It therefore
consumes file descriptors, which can be limited by rlimits and should
therefore be used sparingly.
Switch from EventNotifier to QEMUBH in thread-pool.c. Originally
EventNotifier was used because qemu_bh_schedule() was not thread-safe
yet.

(cherry picked from commit c2e50e3d11a0bf4c973cc30478c1af0f2d5f8e81)
