Bump SoLoader to 0.10.3 (#32922)

Summary:
Closes #32325
Closes #32735

There are various crashes related to the SoLoader (example: #32325, #32735, facebook/SoLoader#74, facebook/SoLoader#84) which [seem to get resolved by](#32325 (comment)) upgrading to [v0.10.3](https://github.com/facebook/SoLoader/releases/tag/v0.10.3).

The upgrade was already done in [`…/soloader/BUCK`](https://github.com/facebook/react-native/blob/main/ReactAndroid/src/main/libraries/soloader/java/com/facebook/soloader/BUCK#L28-L44) (58532ed) but the `SO_LOADER_VERSION` gradle variable was still on v0.10.1.

## Changelog

[Android] [Changed] - Bump Soloader to 0.10.3

Pull Request resolved: #32922

Test Plan: This is my very first RN PR and unfortunately I have troubles running the tests. The [proposed tests](https://github.com/facebook/react-native/wiki/Tests) use Buck anyway and the Buck file was already upgraded so those tests wouldn't change presumably. And I can't get the [`rn-tester`](https://github.com/facebook/react-native/tree/main/packages/rn-tester) to run.
