docs: disambiguate exe_wrapper
As of this commit, meson has three different
pathways to set an exe_wrapper field.
exe_wrapper set through `meson test --wrapper`
CLI arg or `add_test_setup()` meson function argument
are treated equally. Only one wrapper through either
of these routes may be set though.
The exe_wrapper field set in the cross file is handled
separately internally in mtest.py, and holds a little
more consequence over meson test behavior than the other
two fields.
Perhaps a future version of meson should treat these
fields equally and explicitly document how they are
combined.
For now, I think its a better first step to
document current behavior to generate discussion about
how exactly the future version should behave.
