Add support for requester pays with credential_chain

[jterry64]

DuckDB recently added support for AWS requester pays. However it only seems to work when specifying credentials using config proivider with key_id/secret:

CREATE OR REPLACE SECRET secret (
    TYPE s3,
    KEY_ID '<key>',
    SECRET '<secret>',
    REGION 'us-east-1',
    REQUESTER_PAYS true
);

But using it with credentials chain gives: duckdb.duckdb.BinderException: Binder Error: Unknown parameter 'requester_pays' for secret type 's3' with provider 'credential_chain

CREATE OR REPLACE SECRET secret (
    TYPE s3,
    PROVIDER credential_chain,
    CHAIN config,
    REQUESTER_PAYS true
);

This is inconvenient for using it in AWS services with task role-based credentials, where there's not an easy way to directly get explicit key_id/secret tokens.
