Needed to compile Tera Term.

Manual tests show that calling EnableTheming() in uxtheme.dll doesn't update window sizes. So
it seems more appropriate to do it in winecfg.exe.

After applying a theme with CaptionBarHeight set, caption height from SPI_GETNONCLIENTMETRICS is set
to the specified size. However in refresh_sysparams(), the caption height is refreshed and the value
from SM_CXSIZE is used and ends up overwriting the theme specified caption height. SM_CYSIZE is the
correct index instead of SM_CXSIZE.

You may need to turn a theme off and on for the correct caption height to take effect after the fix.

_STRUCT_X86_THREAD_FULL_STATE64 exists, but _STRUCT_MCONTEXT64_FULL and
_STRUCT_MCONTEXT_AVX64_FULL do not.
