Add BinCompat extensions to syntax.apply import

[gagandeepkalra]

This helps with specific import for apply

import cats.syntax.apply._ would now bring ifA to scope

Definitely 👍 to ApplySyntaxBinCompat0, which I think must have been an oversight—thanks for catching it. What's the argument for ParallelApplySyntax, though? We don't do this for any of the other ParallelXSyntax traits.

I see parallel has a separate syntax grouping, thank you @travisbrown
