When enabled, this feature allows games using present interval 0 to run with
truly unlocked FPS, matching actual hardware behavior more accurately.
Previously, Citron would cap present interval 0 at 120FPS to conserve battery,
but this prevented proper functionality of dynamic framerate mods like UltraCam
by MaxLastBreath (https://www.nxoptimizer.com/).
The setting is disabled by default to maintain the current behavior for most users.

Added registration for the 'ssl:s' service using the same implementation as
the regular 'ssl' service. This fixes issues with certain titles that hang indefinitely while
waiting for this service to become available.
The issue appears in logs as:
"Server is not registered! service=ssl:s"
"Waiting for service ssl:s to become available"
This is a simple fix that reuses the existing SSL implementation instead of
creating a separate one, as both services share the same functionality.

This commit enhances the Translation Lookaside Buffer (TLB) implementation
in the ARM Native Code Execution (NCE) component to increase stability,
particularly on Android devices. The changes prioritize robustness and
error recovery over performance optimizations.
Key improvements:
- Replace set-associative TLB with a simpler linear search implementation
- Implement a basic LRU replacement policy for TLB entries
- Add validation checks for memory addresses before TLB insertion
- Ensure proper page alignment for guest and host addresses
- Enhance alignment fault handling with instruction skipping as fallback
- Add comprehensive debug logging for memory access errors
- Improve error recovery in guest memory access scenarios
These changes should significantly reduce crashes during emulation on
Android devices by gracefully handling memory access edge cases that
previously resulted in hard crashes.
