RFR: 8354309: Sort GC includes

[Stefan Karlsson]

We now have a tool to fix our include lines to better adhere to the HotSpot Style Guide. See test/hotspot/jtreg/sources/SortIncludes.java. I've run the tool against the GC code and propose the resulting changes. I did one manual change to move a section guarded with INCLUDE_JFR.

Builds successfully with GHA. I will run this through tier1-2.
