feat(symfony-process): port full Process class from PHP

Faithfully port every method, field and constant of Symfony's
Process.php into process.rs, replacing the reduced stub. Add the
supporting pipes module (PipesInterface/AbstractPipes/UnixPipes/
WindowsPipes), ProcessUtils and the missing process exceptions
(LogicException/InvalidArgumentException) with constructors.

Methods now return anyhow::Result where PHP throws, take the env
argument and a bool-returning callback, and borrow &mut for
status-updating accessors; all callers are updated accordingly.
Extend the php-shim with proc_open/proc_close (PHP-compatible
signatures), proc_get_status, proc_terminate, posix_kill, uniqid,
ftruncate, ftell_stream, fseek3, stream_get_contents3 and env
helpers.
