Notably this allows applications to work that don't require the namespace but check up front if they are able to clone with it.
Civ 6's launcher checks this as an example

Ryan Houdek 4ece56ac4d Fixes uname version string 
This wasn't following the correct format and it never actually had a working FEX_VERSION define.

Scott Mansell 6ed36e3304 Refactor syscalls to take Frame 
The vast majoirty of syscalls don't need anything in thread or frame.
So lets save an indirection for all those syscalls.

Most of the syscalls which do need Thread (or CTX via
Thread are in Thread.cpp or Memory.cpp
These have all been modifiy to fetch Thread from Frame

Adds a new ConfigValues.inl header that defines a few things right next to each other.
Defines the enum name as usual.
Defines the JSON config option name.
Defines the Environment config option name
Defines the default value that the configuration should be
