Speed up adding extensions to an environment
`Environment::addExtension()` recomputes the options hash on every call, JSON-encoding the class names of all the extensions registered so far. This computes it only when a template class name is needed. With the 24 extensions TwigBundle registers on the Symfony Demo, building the environment drops from 87µs to 19µs, and calling `setExtensions()` once instead brings nothing more.
Merge-up to 4.x: the property is typed there, so it has to become `private ?string $optionsHash = null;` (I ran the 4.x suite with that change). The CHANGELOG entry doesn't go to 4.x.

Speed up loading a template that the environment has already loaded
`Environment::load()` allocated a fresh `TemplateWrapper` on every call, even when the template was already loaded. Since `TemplateWrapper` is immutable, the same instance can be reused.
**Performance** (PHP 8.5, interleaved A/B, min of 5 runs):
| Workload | Before | After | |
|---|---:|---:|---:|
| Repeated `load()` of a loaded template | ~800 ns | ~610 ns | **−24%** |
| Page render: layout + 41 `include()` calls | 133 µs | 127 µs | **−5%** |

Allow to call `TemplateWrapper::unwrap()` without arguments
Fixes#4935, symfony/symfony#66193.
#4910 changed an internal API that has famously been used by Symfony since almost forever. We would now need to change Symfony's 5.4 branch which is security-only. Because of that, I'd like to propose to allow calling `TemplateWrapper::unwrap()` without parameters again. This should allow running Symfony 5.4 with the latest Twig 3 again.
We can revert my change on the 4.x branch.

Expose the escaping strategy a template was compiled with
Compiled templates now record the escaping strategy they were compiled with and expose it via `TemplateWrapper::getDefaultEscapeStrategy()`, so the strategy of a template can be known without deriving it again from its name, which is both slower and can disagree with how its content was actually escaped.

Reject template wrappers from another environment
Twig now rejects `TemplateWrapper` instances created by another `Environment`.
This prevents templates from unexpectedly using another environment's loader, extensions, globals, or sandbox policy.
