Python: Disable mem0 telemetry by default

[giles17]

Motivation and Context

Mem0 uses PostHog to collect usage telemetry by default. Users of Agent Framework should not have their usage data sent to third-party analytics services without explicit consent.

Solution
Set MEM0_TELEMETRY=false environment variable before importing the mem0 library. Users can opt-in by setting MEM0_TELEMETRY=true before importing the package.

Resolves #2676

python/packages/mem0/agent_framework_mem0/__init__.py	Sets MEM0_TELEMETRY="false" when not already defined before importing the Mem0 provider, ensuring Mem0’s PostHog telemetry is disabled by default.
python/packages/mem0/agent_framework_mem0/_provider.py	Updates Mem0Provider docstring to explain that telemetry is disabled by default and how to enable it via MEM0_TELEMETRY=true before import.
python/packages/mem0/tests/test_mem0_context_provider.py	Adds telemetry-focused tests to check the default disabled state and that user-provided MEM0_TELEMETRY is honored, but one test relies on external env state and prior imports.
python/packages/mem0/README.md	Documents that telemetry is disabled by default and shows how to enable it using MEM0_TELEMETRY=true before importing agent_framework.mem0.
