This PR improves performance of the PropertyAccess component of ~70%.
The two main changes are:
* caching the `PropertyPath` initialization
* caching the guessed access strategy
This is especially important for the `ObjectNormalizer` (Symfony Serializer) and the JSON-LD normalizer ([API Platform](https://api-platform.com)) because they use the `PropertyAccessor` class in large loops (ex: normalization of a list of entities).
Here is the Blackfire comparison: https://blackfire.io/profiles/compare/c42fd275-2b0c-4ce5-8bf3-84762054d31e/graph
The code of the benchmark I've used (with Symfony 2.3 as dependency):
```php
<?php
require 'vendor/autoload.php';
class Foo
{
private $baz;
public $bar;
public function getBaz()
{
return $this->baz;
}
public function setBaz($baz)
{
$this->baz = $baz;
}
}
use Symfony\Component\PropertyAccess\PropertyAccess;
$accessor = PropertyAccess::createPropertyAccessor();
$start = microtime(true);
for ($i = 0; $i < 10000; ++$i) {
$foo = new Foo();
$accessor->setValue($foo, 'bar', 'Lorem');
$accessor->setValue($foo, 'baz', 'Ipsum');
$accessor->getValue($foo, 'bar');
$accessor->getValue($foo, 'baz');
}
echo 'Time: '.(microtime(true) - $start).PHP_EOL;
```
This PR also adds an optional support for Doctrine cache to keep access information across requests and improve the overall application performance (even outside of loops).

[property-access] Improvement for Accessing Reference Chain
Improve performance for the following scenarios:
- Example 1:
```php
$a = array(
'a' => array(
'b' => array(
'c' => 'old-value'
)
)
);
$pa->setValue($a, '[a][b][c]', 'new-value');
// The PropertyAccessor will try to set values for
// $a['a']['b']['c'], $a['a']['b'] and $a['a'],
// but in fact it may terminate the loop
// right after the value of $a[a][b][c] is set,
// because $a, $[a], $[a][b] and $[a][b][c]
// are all passed as reference - the reference chain is not broken.
```
- Example 2
```php
$b = array(
'a' => array(
'b' => array(
'c' => 'old-value'
)
)
)
$a = new Foo($b);
// In this example, the reference chain of $b is broken,
// because it's passed to $a.value as value
// But its elements are all passed as reference,
// so after setting the value for $b[a][b][c], there is no need
// to set value for $b[a][b] and $b[a]
$pa->setValue($a, 'value[a][b][c]', 'new-value');
```

[PropertyAccess] setValue & isWritable loops must only stops on reference and object. References can also be arrays and if the loop stops the value is never set in the object. (Breaks since 2.6.5 commit e3e4695)
