Faster annotations processing in `ClassLinker::LoadClass()`.

Iterate annotations alongside other method data, using the
fact that both are ordered by method index. We use separate
iterators for loading direct and virtual methods.

For a test class with 500 unannotated static methods and
200 @NeverCompile static methods, this change reduces the
time needed by `ClassLinker::LoadClass` approximately 2x.
For a test class with twice that many methods, the time
without this change increases by ~3x but with this change
the time increases by ~2x, showing nice linear scaling.

Test: m test-art-host-gtest
Test: testrunner.py --host --optimizing
