Check grant type in ValidationTokenRequest

For some reason there's a CheckGrantType on server which is never
actually called to verify whether the grant type is one of the supported
ones.

This adds the check early in the chain to ensure we return a helpful
error when an unsupported grant type is used.

v4.3.1-SSB

Merged updates from upstream.

v4.3.0-SSB

v4.3.0-SSB

This release includes the updates made by SuperSeriousBusiness while adapting the oauth library for use in GoToSocial.

New

• Client and ClientStore are now interfaces rather than structs. This allows library users to implement their own interfaces for these, as is done in GoToSocial. This means that library users are not forced to use in-memory implementations now, but can store values in (for example) a database, so that they persist across application restarts.

Updated

• Client store now deletes entries in its map using Go's delete() function instead of setting the value at that key to nil.
