cratification: start moving over the math commands to nu-cmd-extra (#9647)

* arccos
* arccosh
* arcsin
* arcsinh
* arctan
* arctanh

The above commands are being ported over to nu-cmd-extra

I initially moved all of the math commands over but there are some
issues with the tests...

So we will move them over slowly --- and actually I kind of like this
idea better...

Because some of the math commands we might want to leave in the core
nushell...

Stay tuned...
