* fix: add custom_body parameter to endpoint_func in create_pass_through_route
The bedrock_proxy_route calls `endpoint_func(custom_body=data)` to
pass a pre-parsed, SigV4-signed request body. However, the
`endpoint_func` closure created by `create_pass_through_route` does
not accept a `custom_body` keyword argument, causing:
TypeError: endpoint_func() got an unexpected keyword argument 'custom_body'
Add `custom_body: Optional[dict] = None` to both `endpoint_func`
definitions (adapter-based and URL-based). In the URL-based path,
when `custom_body` is provided by the caller, use it instead of
re-parsing the body from the raw request.
Fixes #16999
* Add tests for custom_body handling in create_pass_through_route
Address reviewer feedback on PR #20849:
- Document why the adapter-based endpoint_func accepts custom_body
for signature compatibility but does not forward it (the underlying
chat_completion_pass_through_endpoint does not support it).
- Add test_create_pass_through_route_custom_body_url_target: verifies
that when a caller (e.g. bedrock_proxy_route) supplies custom_body,
it takes precedence over the body parsed from the raw request.
- Add test_create_pass_through_route_no_custom_body_falls_back:
verifies that the default path (no custom_body) correctly uses the
request-parsed body, preserving existing behavior.
Both tests are fully mocked following the project's CONTRIBUTING.md
guidelines and the patterns established in the existing test file.
