f368b91caf light: minor fixes / standardising errors (#5716)
## Description

I'm just doing a self audit of the light client. There's a few things I've changed

- Validate trust level in `VerifyNonAdjacent` function
- Make errNoWitnesses public (it's something people running software on top of a light client should be able to parse)
- Remove `ChainID` check of witnesses on start up. We do this already when we compare the first header with witnesses
- Remove `ChainID()` from provider interface

Closes: #4538

a08316f16a light: use bisection (not VerifyCommitTrusting) when verifying a head… (#5119)
Closes #4934

* light: do not compare trusted header w/ witnesses

we don't have trusted state to bisect from

* check header before checking height

otherwise you can get nil panic
