pulse-server: module: rework registry

Browse source 
Move all module methods into the `module_info` struct, and place
all such structs into the "pw_mod_pulse_modules" section of
the executable. This way there is no need for an explicit
module registry, and all information about a module can
be declared in the module's source file in a single place.
