fix(input): thread a typed InputValue through the input layer

Options and arguments were stored and passed as PhpMixed even though
Symfony only ever puts a string, a bool, a list of strings or null in
one. get_option already narrowed to InputOptionValue at the boundary;
this widens that enum into InputValue and pushes it through
InputInterface, InputOption/InputArgument defaults, the Input storage,
ArgvInput/ArrayInput/StringInput/CompletionInput, Command::add_option
and add_argument, and the Composer-side wrappers.

Two neighbouring string|int unions get types of their own:
InputDefinition::{get_argument,has_argument} take an ArgumentName, and
ArrayInput keys its parameters by ParameterName. has_parameter_option
and get_parameter_option take the values they look for as &[&str],
which is what PHP's `(array) $values` cast produced anyway.

Two behaviours change along the way. Input::set_option on a negated
option now negates with PHP's loose bool cast rather than treating a
non-bool as false, matching `!$value`. ArrayInput::parse now resolves
an integer key to an argument position instead of looking up an
argument literally named "0".
