OpcodeDispatcher: Implement SLDT
...
Not 100% correct because the Linux kernel has some cheeky false data
return value when an LDT gets installed. But FEX can't really do it
properly today so whatever.

HostFeatures: Make a stronger distinction between CPU features and Process features
...
We want to have two distinct control knobs here. CPU features that don't
change between Linux, Wow64, Arm64ec, and additional options that change
depending on the process environment.
This distinction was a /bit/ muddy where I added
`SupportsFaultFreeSynchronousFaults` to the wrong side of that. Make it
more distinct by logically splitting it out so that HostType, the
fault-free-faults, and added Is64BitMode all lives together.
This lets the DiskCache code which is hashing these variables look a bit
nicer and also correctly logically separate the two halves.

Useful debug feature to make sure FEX returns consistent flag data for
instructions that have undefined flags. Just sets everything that is
undefined to zero always.
Manually walked through all the instructions in the architecture manual
to check for ones doing undefined flag setting, then glued the handler
on to the end.
Also fixes a comment that has incorrect information about undefined
flags.
