fix: delete the go formatter code as it is not longer used

[skartikey]

removed ast/format.go and ast/format_test.go
also removed test_rewriter package as its not longer in use

Looks good, are you going to also make sure that the other repositories that use Flux can still build with the Go formatter removed?

As an aside, I don't think we need this code anymore... we should delete it.

(I don't mean for you to delete as part of this PR)

I can see go formatter reference in idpe, kapacitor and query-archiver
In idpe, a big chunk of replacement has already been done by this PR https://github.com/influxdata/idpe/pull/10481
only a few occurrences are left.

I have sent a message on bulletins and will make sure all the references are replaced before merging this PR.

The remaining occurrences of ast.Format in kapa are from a different ast package (for TICKscript)
