NEW: Add LocationSensor for Input System

[MorganHoarau]

Description

Addresses ISX-2227 is part of the Input Manager parity epic ISX-2108.

This PR is the managed layer only. Refer to the native bridge PR here.

Add a LocationSensor device that exposes the device's GPS and lifecycle through the standard Input System surface:

• Readings as event-driven controls: latitude, longitude, altitude, horizontalAccuracy, verticalAccuracy, timestamp.
• Lifecycle via InputSystem.EnableDevice / DisableDevice + status and isEnabledByUser as query properties.
• Configure(desiredAccuracyInMeters, updateDistanceInMeters) + ResetConfiguration(), with project defaults InputSettings.locationAccuracy / locationDistanceThreshold (both 10, matching legacy Start()), surfaced in Project Settings.

Backed by the shared native LocationService.

Documentation Impact

• Public API added (LocationSensor + controls + status / isEnabledByUser / Configure / ResetConfiguration, InputSettings.locationAccuracy / locationDistanceThreshold, three public command structs). All carry XML docs.
• Migration table updated: Documentation~/corresponding-old-new-api.md now maps Input.location -> LocationSensor with a usage snippet.

Testing status & QA

Please describe the testing already done by you and what testing you request/recommend QA to execute. If you used or created any testing project please link them here too for QA.

ℹ️ PLEASE READ: Parity testing summary document

• 6 unit tests added (CoreTests_Devices.cs): reading, status, isEnabledByUser, fallback path (no native impl), Configure, ResetConfiguration.
• On-device (via the InputFeatureParity Validation project):
  • Tested on Android, iOS and Web (Windows, Mac, Android and iOS) in both input backend "Both" and "Input System (new)".

Overall Product Risks

Please rate the potential complexity and halo effect from low to high for the reviewers. Note down potential risks to specific Editor branches if any.

• Complexity: 1
  • Additive, self-contained device; fallback to Stopped / false where no native impl exists (editor/desktop), so no regression to existing sensors.
• Halo Effect: 1
  • Touches shared InputSettings (two new serialized fields + settings UI).

Comments to reviewers

Please describe any additional information such as what to focus on, or historical info for the reviewers.

💡 Harness Review

The new sensor implementation generally aligns with surrounding sensor, command, and settings patterns, while the associated migration guidance needs correction.
