This improves the tests and docs for a few functions, specifically `E`,
`FLOOR`, `PI`, `POW`, and `ROUND`. The examples and tested signatures
will get copied into the docs and kibana signatures.

This merges all of the hand written docs for `LOG` and `LOG10` into the
annotations which updates the `META FUNCTIONS` - now it'll always be the
same as the docs. This also deletes the hand maintained docs and let's
the documentation generation process rebuild it.
This updates the in-code docs on the trig functions to line up with the
docs, removes the docs, and uses the now mostly identical generated
docs. This means we only need to document these functions in one place -
right next to the code.
