Review Comment:
could we use a dialect method for the feature flag? so that this becomes
e.g. `if self.dialect.supports_empty_projections() &&
self.peek_keyword(Keyword::FROM)`

Review Comment:
if we use a dialect method suggesed above we'd likely want to move this to
common and be able to write the test using
[all_dialects_where()](https://github.com/apache/datafusion-sqlparser-rs/blob/bcdc790b0135dc64ec4d40eaa837316530a5f5f3/tests/sqlparser_common.rs#L4981)
