RFR: 8257731: Remove excessive include of stubRoutines.hpp [v2]

[Ioi Lam]

> stubRoutines.hpp is unnecessarily included by thread.hpp and copy.hpp. This causes a large number of header files related to native code generation to be included by almost all HotSpot .o files.
> 
> - Before the fix, stubRoutines.hpp is included by 803 .o files.
> - After the fix, stubRoutines.hpp is included by 117 .o files.
> 
> The total number of included header files decreased from 252893 to 247631, or about 2%.
> 
> Note: the main change is the removal of stubRoutines.hpp in thread.hpp and copy.hpp. Unfortunately I have to fix quite a few missing dependencies in other source files that are revealed by the removal.
> 
> Testing: I've tested tier1, builds-tier2, builds-tier3, builds-tier4 and builds-tier5 on mach5, plus locally building arm, aarch64, s390, ppc64, and zero.
