[8u40] RFR(s): backport of 8058184, 8058092

8058184: Move _highest_comp_level and _highest_osr_comp_level from MethodData to MethodCounters
The patch did not apply automatically because 8u doesn’t have code aging that added new field to MethodCounters. Since the patch had to
be adjusted manually I also moved _highest_*_level fields in MethodCounters to achieve optimal packing (not a problem for 9, packing there is optimal already).
