configure: add --enable-builtin-codecparsers [default="yes"] option.

Add flag to have all codecparsers built-in, thus ensuring that the
resulting binaries have all the necessary bug fixes and this is what
the QA has been testing anyway.

Of course, for a completely up-to-date Linux distribution, you could
also opt for --disable-builtin-codecparsers and use the system ones.
Though, some core fixes could be missing, and those cannot be tested
for with API checks.
