[FEATURE] Add profile feature to AgentCoreBrowser

[shasti421]

Problem Statement

Support for newly released browser profile feature in Bedrock AgentCore.

https://docs.aws.amazon.com/bedrock-agentcore/latest/devguide/browser-profiles.html

Proposed Solution

One approach would be to add optional arg to init https://github.com/strands-agents/tools/blob/main/src/strands_tools/browser/agent_core_browser.py#L24
profile_configuration: Optional[Dict]

Change in bedrock_agentcore.tools.browser_client.BrowserClient.start to take profile_configuration as optional arg and add to request_params before calling data_plane_client.start_browser_session

if profile_configuration is not None:
            request_params["profileConfiguration"] = profile_configuration

https://github.com/aws/bedrock-agentcore-sdk-python/blob/main/src/bedrock_agentcore/tools/browser_client.py#L331

Use Case

Ability to use AWS Browser profile support in AgentCoreBrowser with Strands Agents

AgentCoreBrowser(
        region="us-east-1",
        identifier="browser-2456",
        session_timeout=300,
        profile_configuration={
           "profileIdentifier": "salesforce_profile"
         },
    )
