Ryan Houdek 9ba46f429e X8764: Ensure frndint uses host rounding mode ...

This previously used `Round_Nearest` which had a bug on Arm64 that it
actually was always using `Round_Host` aka frinti.
Ever since 393cea2e8ba47a15a3ce31d07a6088a2ff91653c[1] this has been fixed
so that `Round_Nearest` actually uses frintn for neaest.

This instruction actually wants to use the host rounding mode.
Once issue with this is that x87 and SSE have different rounding mode
flags and currently we conflate the two in our JIT. This will need to be
fixed in the future.

In the meantime this restores behaviour that it actually uses the host
rounding mode, which fixes black screen and broken vertices in Grim
Fandango Remastered.
