cratification: part III of the math commands to nu-cmd-extra (#9674)

The following math commands are being moved to nu-cmd-extra

* e (euler)
* exp
* ln

This should conclude moving the extra math commands as discussed in
yesterday's
core team meeting...

The remaining math commands will stay in nu-command (for now)....
