FEXCore: Remove Context header include when unneeded

This is one of the most expensive headers in FEX, averaging 1.2 seconds
of compile time per include.
We include this header 31 times around the project. Remove
the five instances where it is unused to help this issue. Next step
would be to make the header lighter if possible.
