*Description of changes:*

This PR applies temporary patches to address critical bugs in the AWS
Bedrock runtime botocore instrumentation (version 0.54b0) that affect
tool use functionality in non-streaming responses reported in:
strands-agents/sdk-python#488

These changes are temporary patches and should be removed once we
upgrade to `opentelemetry-instrumentation-botocore` version 0.56b0,
which includes official fixes for these issues.

See: 
open-telemetry/opentelemetry-python-contrib#3548
open-telemetry/opentelemetry-python-contrib#3544

*Testing Done*

- Unit tests added
- Validated with Bedrock AgentCore team that fixes work.
- Ran a sample app with Bedrock AgentCore and strands framework and
validated that expected toolUse output is correct:

Before fix:

```
Tool use: {"input": ""}
Tool use: {"input": "{\"input\": 99"}
Tool use: {"input": 999}
Tool use: {"input": 99999}
Tool use: {"input": 9999}
Tool use: {"input": 9999}
Tool use: {"input": ", \"input2"}
Tool use: {"input": "\": 8"}
Tool use: {"input": 888888888888}
Tool use: {"input": 888}
Tool use: {"input": "88}"}
```

After fix:

```
Tool use: {"input": ""}
Tool use: {"input": "{\"in"}
Tool use: {"input": "put\": 9"}
Tool use: {"input": "99"}
Tool use: {"input": "99"}
Tool use: {"input": "99"}
Tool use: {"input": "9999"}
Tool use: {"input": "99999"}
Tool use: {"input": "99"}
Tool use: {"input": ", \"input"}
Tool use: {"input": "2\":"}
Tool use: {"input": " 8"}
Tool use: {"input": "888888"}
Tool use: {"input": "888888888"}
Tool use: {"input": "88}"}
```

We need to accumulate all the tool input as string before decoding it
otherwise we may end up with invalid json.
