chore(deps): update Native SDK to v0.12.4

[github-actions]

Bumps modules/sentry-native from 0.12.3 to 0.12.4.

Auto-generated by a dependency updater.

Changelog

0.12.4

Fixes:

• Crashpad: namespace mpack to avoid ODR violation. (#1476, crashpad#143)
• Structured logs: stop local attributes overwriting all globally set attributes. They now get merged, and local values overwrite existing global values for the same key. (#1486)
