feat: String interpolation in structured logging

[limbonaut]

This PR adds support for string interpolation and attributes in the structured logging API. Supports Godot string formatting syntax.

Usage:

# Simple usage
SentrySDK.logger.debug("Spawning enemies with 5 units")

# With parameters and attributes
SentrySDK.logger.debug("Spawning %s with %d units", ["enemies", 5], {
	"level": "forest_1",
	"wave_id": "wave_3"
})

• Depends on feat(logs): custom attributes API sentry-native#1435
• Waiting for sentry-native release. Waiting done.

TODOs:

• Docs PR feat(godot): Document string interpolation and attributes in logging API sentry-docs#15751
