RFR: 8253271: vm_version_x86.hpp should not include globals_extension.hpp

[Ioi Lam]

[vm_version_x86.hpp](https://github.com/openjdk/jdk/blob/b87a1599674b8a73f489330decf051d1be9e9fba/src/hotspot/cpu/x86/vm_version_x86.hpp#L30)
is a popular header file (which in itself is a problem but I'll fix that in a separate RFE) and it unnecessarily
includes globals_extension.hpp.

Removing this dependency reduces the number of cpp files that include globals_extension.hpp from 814 to 67.

I need to fix cpp files that use macros like FLAG_SET_ERGO but forgot to include  globals_extension.hpp.
