Part of rectorphp/rector#9965, split from #827.

PHPUnit counts assertions made in lifecycle methods toward every test of the class. A test whose own body asserts nothing still "performs assertions" when setUp(), tearDown(), assertPreConditions(), assertPostConditions(), a #[Before]/#[After]/#[PreCondition]/#[PostCondition] method or a @before/@after/@preCondition/@postCondition method asserts. With failOnRisky, the added #[DoesNotPerformAssertions] then fails the test.

Change

New LifecycleMethodAssertAnalyzer, which checks only the lifecycle methods of the test's own class:

• The class is taken from the current file's AST (getFile()->getNewStmts()), so nothing is parsed again. No AstResolver for ancestors or traits here, that stays in [PHPUnit60] Skip tests in classes with asserting lifecycle methods in AddDoesNotPerformAssertionToNonAssertingTestRector #827.
• Calls inside the hooks are followed by AssertCallAnalyzer as before (helpers, parent::setUp()).
• The result is cached per Class_ node, so all test methods of a class share it.

Bench

New bench/does_not_perform_assertion_own_lifecycle_bench.php: 300 test classes with own setUp() and tearDown(), every other one asserting in setUp(). The existing lifecycle bench now sets the current File on CurrentFileProvider, like AbstractRectorTestCase does, as the rule reads it. CPU, 3 runs, local:

bench	main	this PR
own lifecycle	0.29-0.35 s	0.29-0.31 s
lifecycle (deep chains)	1.29-1.39 s	1.31-1.32 s

Without the per-class cache the own-lifecycle bench was ~0.44 s.
