fix(autoload-generator): survive listeners that re-enter dump()

AutoloadGenerator::dump dispatches PRE_AUTOLOAD_DUMP / POST_AUTOLOAD_DUMP, and
EventDispatcher::make_autoloader answers those by walking back into the Composer
graph -- the local repository, the installation manager, and the generator
itself. Installer::run held mutable borrows of all three across the dump call,
so any plugin subscribing to either event panicked with "RefCell already
borrowed" before its listener ran.

dump() and build_package_map() now take the local repository, the installation
manager and the locker as shared handles instead of &mut dyn, and the borrow is
taken where it is used.

The generator itself is re-entered, not just borrowed twice: PHP listeners reach
it through Composer::getAutoloadGenerator() and call setDevMode() while dump()
is running, and make_autoloader asks the same object for a package map. That is
not expressible behind &mut self, so the mutable state moves into Cell/RefCell
fields and the whole AutoloadGeneratorInterface takes &self.
