[Canvas] Added formatnumber and formatdate UIs to sidebar

[cqliu1]

Summary

Closes #23111.
Closes #23112.

This introduces a dateformat argument form for the sidebar. It looks identical to the numberFormat argument type introduced in #42007 but handles MomentJS formats instead of NumeralJS formats.

For expressions that include formatdate or rounddate as one of the functions, this form will appear in the sidebar.

Note: Currently the sidebar isn't populated with forms for functions used in sub-expressions, so if you have something like | mapColumn @timestamp fn={getCell @timestamp | formatdate "MM/DD/YYYY"}, you won't see this date format form in the sidebar and will still need to change it via the expression editor.

Changes:

• adds a dateformat argument type
• adds transform UIs for formatnumber, formatdate, and rounddate
• adds stories for new components
• adds argument type defs
• adds transform type defs

LGTM, works great!!

For those testing, here is a little expression to get a date which can be formatted via this new sidebar UI:

date
| math "value - 1000*60*60*7"
| formatdate "dddd, MMMM Do YYYY, h:mm:ss a"
| markdown {context}
| render

Just one minor thing regarding proptypes. Looks great overall!

I think these two props might be out of date
