okhttp: enable TLS 1.3 on Android, retain TLS 1.2-only for desktop JVM

The ConnectionSpec used by OkHttpChannelBuilder had TLS 1.3 explicitly
disabled since Dec 2020 due to a Conscrypt/SunJSSE incompatibility.
However, this incompatibility does not affect Android. The previous code
applied the TLS 1.2-only restriction unconditionally to all platforms.

Regulatory impact: TLS 1.2 is classified as a legacy mechanism in ENISA
Agreed Cryptographic Mechanisms v2.0 (April 2025), with TLS 1.3 listed
as the recommended protocol. This limitation has been forcing all
downstream components using grpc-okhttp on Android to operate with a
legacy protocol, creating compliance friction with the EU Radio
Equipment Directive (RED) and EU Cyber Resilience Act (CRA)
certification requirements.

Fixes: https://github.com/grpc/grpc-java/issues/7431 (Android only)
Fixes: https://github.com/grpc/grpc-java/issues/7765 (Android only)
