Swap StaticReflectionParser for PhpParser in HookCollectorPass

Unfortunately this doesn't help, it is just slower.

Locally a standard install on 11.x is [11.47 sec, 252.17 MB]

With this change it is [14.92 sec, 252.74 MB]

Leaving this code here in case it is useful elsewhere where we want to avoid using token_get_all().

nikic/php-parser uses token_get_all or in php8 the newly introduced PhpToken but both of those call the Zend C function tokenize_common so that's pretty much the same. if the problem is in the Zend tokenizing system then changing the call chain to it won't help.

Yeah, I think this is a false positive, it's not token_get_all() that's the problem - rebuilding the container does leak memory somewhere, but this isn't it.
