Enable TLS Fingerprinting configuration (JA3/JA4)

[WUMUXIAN]

internal/(envoy): Make it possible to enable TLS fingerprinting in Envoy's TLS Inspector Listener filter, useful for security monitoring, analytics, and bot detection. Provides independent control over JA3 and JA4 fingerprinting methods.

enableJA3Fingerprinting: Enable JA3 fingerprinting (requires Envoy 1.21.0+)
enableJA4Fingerprinting: Enable JA4 fingerprinting (requires Envoy 1.35.0+)
Both settings default to false.

Updates #7307
Release note: release-note/minor
