fix(logs): optimize LogRecord memory by removing redundant context

Removed direct storage of the Context object in LogRecord to prevent
memory inflation when logs are buffered. Correlation IDs (TraceId,
SpanId, TraceFlags) are still preserved.

Resolves #4957

 ## Unreleased
 
+- `opentelemetry-api`: Optimize `LogRecord` memory by removing direct storage of the `Context` object.
+  ([#4957](https://github.com/open-telemetry/opentelemetry-python/issues/4957))
 - `opentelemetry-sdk`: Add file configuration support with YAML/JSON loading, environment variable substitution, and schema validation against the vendored OTel config JSON schema
   ([#4898](https://github.com/open-telemetry/opentelemetry-python/pull/4898))
 - Fix intermittent CI failures in `getting-started` and `tracecontext` jobs caused by GitHub git CDN SHA propagation lag by installing contrib packages from the already-checked-out local copy instead of a second git clone
