Including the 'caller' field in 'tool_use' blocks within input
messages causes API errors (especially for computer-use) because
the API expects only standard fields like id, name, type, and input.
This field was recently added to the SDK models and parameters but
should not be sent back to the API.
This PR:
1. Removes 'caller' from BetaToolUseBlockParam and
BetaServerToolUseBlockParam.
2. Adds __api_exclude__ = {"caller"} to BetaToolUseBlock and
BetaServerToolUseBlock models.
3. Modifies the internal transformer to explicitly strip 'caller'
if it's not annotated in a TypedDict, ensuring raw dicts or
unfiltered model dumps don't leak it back to the API.

Vertex/Bedrock clients map beta headers to the request body. This PR updates the streaming accumulation logic to check the request body for flags like \ ine-grained-tool-streaming-2025-05-14\ when headers are missing. Fixes #1020
