feat(zend): add ModuleGlobals for per-extension global state

Add `ModuleGlobal` trait and `ModuleGlobals<T>` struct that integrate
with PHP's TSRM to provide per-extension module globals. In ZTS builds,
PHP allocates per-thread storage via `ts_allocate_id`; in NTS builds,
the globals live inline in a user-declared static.

API surface:
- `ModuleGlobal` trait: `Default + 'static` with optional `ginit`/`gshutdown`
- `ModuleGlobals<T>::new()`: const constructor for static declaration
- `ModuleGlobals<T>::get()`: safe shared access (PHP single-threaded request model)
- `ModuleGlobals<T>::get_mut()`: unsafe mutable access
- `ModuleGlobals<T>::as_ptr()`: raw pointer escape hatch
- `ModuleBuilder::globals()`: registration via existing builder pattern

C layer: `ext_php_rs_tsrmg_bulk()` wraps `TSRMG_BULK` macro for ZTS access,
matching the existing pattern for executor/compiler/process globals.
