Description

while adding connectors we need to implement intermediate traits while allow us to implement ConnectorIntegration. Example of such implementations are:

impl api::Payment for Stripe {}

impl api::PaymentAuthorize for Stripe {}
impl api::PaymentSync for Stripe {}
impl api::PaymentVoid for Stripe {}
impl api::PaymentCapture for Stripe {}
impl api::PaymentSession for Stripe {}
impl api::ConnectorAccessToken for Stripe {}

create a declarative macro to automate this, and other such implementations

Research direction
This issue involves creating declarative macros in Rust to automate the implementation of intermediate traits for connectors, such as `api::Payment` and `api::PaymentAuthorize`. The expected location for the macros is likely within the `crates/router/src/connector/` directory, possibly in a new `macros.rs` file. The contributor should first study existing connector implementations to understand the pattern, then design a macro that reduces boilerplate. The issue has an assignee; check comments for any initial work or suggestions.
