Update print warning script for low priority warning (#9756)

* Add back caught error and other checks to 'lowPriorityWarning'

**what is the change?:**
This change makes 'lowPriorityWarning' an exact copy of 'warning.js' from
https://github.com/facebook/fbjs/blob/e66ba20ad5be433eb54423f2b097d829324d9de6/packages/fbjs/src/__forks__/warning.js
where before we had skipped some checks from that module.

- Adds an error which we catch, in order to let people find the error and resulting stack trace when using devtools with 'pause on caught errors' checked.
- Adds check that 'format' argument is passed

**why make this change?:**
- To maintain a closer fork to 'warning.js'
- To allow easier debugging using 'pause on caught errors'
- To validate inputs to 'lowPriorityWarning'

**test plan:**
`yarn test`

**issue:**

* Update 'print-warnings' script to include 'lowPriorityWarning' output

**what is the change?:**
We print the logs from 'lowPriorityWarning' as well as 'warning' from the 'print-warnings' script.

NOTE: This PR is branching off of #9754

**why make this change?:**
We want to use the same process of white/blacklisting warnings with 'lowPriorityWarning' that we do with 'warning'.

**test plan:**
This is not super easy to test unless we are doing a sync with FB afaik. I plan on running a sync in the next few days, or next week at latest, for the sake of not landing big things on a Friday. That will be the actual test of this.

**issue:**
#9398
