worker_spi: Use term "dynamic" for bgworkers launched with worker_spi_launch()

This gives a way to make a difference between workers registered when
the library is loaded with shared_preload_libraries and when these are
launched dynamically, in ps output or pg_stat_activity.

Extracted from a larger patch by the same author.
