This adds an AuthenticatorAttachment field to
CtapMakeCredentialRequest. The field is initialized by
MakeCredentialRequestHandler from the equivalent field on its
AuthenticatorSelectionCriteria parameter, and is consumed by
WinNativeApiAuthenticator to initialize the equivalent parameter passed
to the Windows WebAuthn API.

Also moves the AuthenticatorAttachment enum out of
AuthenticatorSelectionCriteria and into fido_constants.h, and fixes a
common misspelling of attachment throughout the code.

Also migrates the allowList and excludeList parameters of the Windows
WebAuthn API to an updated version that respects the
PublicKeyCredentialDescriptor's transports field.
