bitbake: use multiple processes to dump signatures.

This change significantly shortens the time on reparsing stage
of '-S' option.

Each file is reparsed and then dumped within a dedicated
process. The maximum number of the running processes is not
greater than the value of BB_NUMBER_PARSE_THREADS if it is set.

The dump_sigs() in class SignatureGeneratorBasic is _replaced_
by a new dump_sigfn() interface, so calls from the outside and
subclasses are dispatched to the implementation in the base
class of SignatureGeneratorBasic.

Fixes [YOCTO #10352]
