* @mfmarche on 24 Feb: when code_verifier is set, don't check client_secret
In PKCE flow, no client_secret is used, so the check for a valid client_secret
would always fail.

* PKCE: Check clientSecret when available
In authorization_code flow with PKCE, allow empty client_secret on /auth and /token endpoints. But check the client_secret when it is given.

* Enable PKCE with public: true
dex configuration public on staticClients now enables the following behavior in PKCE:
- Public: false, PKCE will always check client_secret. This means PKCE in it's natural form is disabled.
- Public: true, PKCE is enabled. It will only check client_secret if the client has sent one. But it allows the code flow if the client didn't sent one.

Now, we'll return a standard error, and have the caller act upon this
being an instance of authErr.
Also changes the storage.AuthRequest return to a pointer, and returns
nil in error cases.

The "at_hash" claim, which provides hash verification for the
"access_token," is a required claim for implicit and hybrid flow
requests. Previously we did not include it (against spec). This
PR implements the "at_hash" logic and adds the claim to all
responses.
As a cleanup, it also moves some JOSE signing logic out of the
storage package and into the server package.
For details see:
https://openid.net/specs/openid-connect-core-1_0.html#ImplicitIDToken
Accept the following response_type for the implicit flow:
id_token
token id_token
And the following for hybrid flow
code id_token
code token
code token id_token
This corrects the previous behavior of the implicit flow, which
only accepted "token" (now correctly rejected).
go-oidc sends an extra space before the list of scopes. This is bad
but we have to support it, so we'll be more lenient and ignore
duplicated whitespace.
