[TomasVotruba]

Adds a PHPUnit extension that measures each test method duration and prints the slowest ones at the end of the run.

• registers 3 event subscribers (prepared, finished, execution finished)
• groups all data-provider fixtures under their test method, so a slow rule shows as one entry
• prints the top 25 tests slower than 0.5s, sorted descending

Example output on rules-tests/DeadCode:

4 slowest tests (>= 0.5s):
  1.   1.10s  ...RemoveUnusedPrivateMethodRectorTest::test
  2.   0.96s  ...RemoveUnusedVariableAssignRectorTest::test
  3.   0.84s  ...RemoveAlwaysTrueIfConditionRectorTest::test
  4.   0.79s  ...RemoveDoubleAssignRectorTest::test

Fast runs print nothing, so normal output stays clean.
