Description

Follow-up to #32315 to add fields to google_grpc to support setting minimum and maximum TLS versions explicitly. Note this has impact on Wasm ABI, since this proto is used to make RPCs.

Contributor guide

Research direction
Add min tls version and max tls version fields to the GoogleGrpcService proto in api/envoy/extensions/transport sockets/tls/v3/common.proto, update the xDS configuration handling in source/common/grpc/google grpc service.cc, and ensure Wasm ABI compatibility. Refer to PR #32315 for context and the existing pattern for TLS version fields.
