mjit.h: introduce MJIT_STATIC for full mswin JIT support

This change resolves most of major remaining MJIT bugs on mswin.
Since Visual Studio doesn't support generating pre-processed code
preserving macros, we can't use transform_mjit_header approach for mswin.
So we need to transform MJIT header using macro like this.

vm.c: use MJIT_STATIC for non-static functions that exist on MJIT header
and cause conflict on link.
vm_insnhelper.c: ditto

test_jit.rb: remove many skips for mswin.
