Method getMockForAbstractClass() of class PHPUnit\Framework\TestCase is deprecated in PHPUnit 10 - Step 1 interfaces

Let's do a first step and target the usage of the method to create mocks against interfaces - which is nonsense (probably leftover from earlier conversions/creation of interfaces): when you mock an interface you create anyway doubles for all the methods declared on the interface. No abstract classes here, really.

Like the approach, like the MR, but we've might have a few stragglers (at least, if I understand the scope correctly):

- \Drupal\Tests\Component\Plugin\Discovery\StaticDiscoveryDecoratorTest::testGetDefinition: https://git.drupalcode.org/project/drupal/blob/b73c68de45491739c0752d859... and https://git.drupalcode.org/project/drupal/blob/b73c68de45491739c0752d859...
- \Drupal\Tests\Core\Entity\Sql\SqlContentEntityStorageTest::testLoadMultiplePersistentCached: https://git.drupalcode.org/project/drupal/blob/654b1f2074ea90b75a8750f2b...
- \Drupal\Tests\Core\Entity\Sql\SqlContentEntityStorageTest::testLoadMultipleNoPersistentCache: https://git.drupalcode.org/project/drupal/blob/654b1f2074ea90b75a8750f2b...
- \Drupal\Tests\Core\Entity\Sql\SqlContentEntityStorageTest::testLoadMultiplePersistentCacheMiss: https://git.drupalcode.org/project/drupal/blob/654b1f2074ea90b75a8750f2b...
- \Drupal\Tests\Core\Entity\TypedData\EntityAdapterUnitTest::setUp: https://git.drupalcode.org/project/drupal/blob/9add7f71ff26864477f80e349...

Thanks @Spokje, the first two OK, indeed; the last three in fact are misleading since in each file SqlContentEntityStorageTestEntityInterface is an abstract class defined at the end of each file... very confusing, for that one we need an issue of its own.

Fixing the first two.

Thanks @mondrake, I'll take a 50% success rate any day...

RTBC for me now.

Backported to 10.2.x to keep tests aligned.
