RFR: 8310225: Reduce inclusion of oopMapCache.hpp and generateOopMap.hpp

[Ioi Lam]

These includes aren't necessary and should be removed:

frame_x86.inline.hpp -> oopMapCache.hpp -> generateOopMap.hpp.

Before:
frame_x86.inline.hpp included 571 times
oopMapCache.hpp included 571 times
generateOopMap.hpp included 571 times

After:
frame_x86.inline.hpp included 571 times
oopMapCache.hpp included 21 times
generateOopMap.hpp included 21 times
