service/ssl: Add ssl:s service and fix SSL-related crashes in Xenoblade X

Browse Source 
Implements the ssl:s service alongside various SSL-related functionality that
was causing Xenoblade Chronicles X: Definitive Edition to crash. The changes
include:

- Add the ssl:s service with proper command handlers
- Add InfoType::TLSCapability (0x1C) to the system call handler
- Implement a stub SSL backend for basic network operations
- Add FlushSessionCache functionality to both ssl and ssl:s services

These changes resolve the "TLS initialization failed" crash and the "Unknown
function '5': port='ssl:s'" error that were preventing the game from starting.
The implementation is mostly stubbed, allowing network requests to pass through
unencrypted but enabling games to proceed without crashing.
