Embeds #26929, #27009 and #27028, let's focus on the 4th commit for now.
This is my last significant PR in the Cache series :)
By using integer expiries internally, our current implementations are sensitive to abrupt transitions when time() goes to next second: `$s = time(); sleep(1); echo time() - $s;` *can* display 2 from time to time.
This means that we do expire items earlier than required by the expiration settings on items.
This also means that there is no way to have a sub-second expiry. For remote backends, that's fine, but for ArrayAdapter, that's a limitation we can remove.
This PR replaces calls to `time()` by `microtime(true)`, providing more accurate timing measurements internally.

[Cache] Add stampede protection via probabilistic early expiration

This PR implements [probabilistic early expiration](https://en.wikipedia.org/wiki/Cache_stampede#Probabilistic_early_expiration) on top of `$cache->get($key, $callback);`
It adds a 3rd arg to `CacheInterface::get`:
> float $beta A float that controls the likelyness of triggering early expiration. 0 disables it, INF forces immediate expiration. The default is implementation dependend but should typically be 1.0, which should provide optimal stampede protection.

This is a proof-of-concept. Once we agree / are happy, I need to add this to all of the other authentication mechanisms that recently got the session migration code & add tests.
Basically, this avoids migrating the session if the firewall is stateless. There were 2 options to do this:
A) Make the `SessionAuthenticationStrategy` aware of all stateless firewalls. **This is the current approach**
or
B) Make each individual authentication listener aware whether or not *its* firewall is stateless.

In xml when parent node (`restaurants`) contains several children nodes with the same tag (`restaurant`) it is clear that the children form a collection:
```
restaurants = {array} [1]
restaurant = {array} [2]
0 = {array} [2]
name = "Some restaurant name"
type = "Chinese"
1 = {array} [2]
name = "Another restaurant name"
type = "Italian"
```
Afterwards the object denormalizer has no problem to create a collection of restaurants.
But when there is only one child (`restaurant`) the decoded normalized array will not contain a collection:
```
restaurants = {array} [1]
restaurant = {array} [2]
name = "Some restaurant name"
type = "Chinese"
```
In this situation the object denormalizer threw unexpected exception. This PR modifies `AbstractObjectNormalizer` that is it will fill a collection containing the sole element properly.

This PR remove the semaphore with `sem_remove`. By removing without releasing the semaphore, all pending blocking acquiring will fail that's why the acquire method has also been update to handle such case
