[Hurlicane-Aary] split external account request and response schemas for paymentRails

Remove paymentRails from the create external account request schema while
keeping it in the response. Each common *AccountInfo is now split into a
*AccountInfoBase (without paymentRails) and *AccountInfo (allOf composition
with paymentRails). Request schemas reference *AccountInfoBase via new
*ExternalAccountCreateInfo files, while response schemas still use the full
*AccountInfo with paymentRails.
