[WebGL] [wasm] Uncaught RuntimeError exception is thrown when calling a native function from a static linked library
Reproduction steps:
1. Open the project from the GitHub repository provided by the user
2. Switch Platform to WebGL in Build Settings
3. Build and Run
4. Wait for the build to run
Expected result: A Cube with a Texture applied to its Material can be seen
Actual result: Running the build fails and errors are logged in the browser: "Uncaught RuntimeError: null function or function signature", "An abnormal situation has occurred: the PlayerLoop internal function has been called recursively"
Reproducible with: 2021.2.2f1, 2022.1.0a15
Could not test with: 2019.4.32f1, 2020.3.23f1, 2021.1.28f1 (namespace and native library errors after downgrade)
Note:
- Not reproducible in Development Build
- The tested native library supports only WebGL (f. e. it would error in Play Mode)

I've added commit that makes native plugin work to reproduce this bug in 2022.2.0b3
1) take my repo
2) checkout commit under tag WorksInDevBuild_2022.2.0b3
3) try to build in development mode: it works
4) try to build without development mode: it throws exception.
p.s. the error will be in both dev/nondev modes if ThrowExceptions is not set to None.

p.s. I recommend to build from the tag "Unity2021.2.0f1_DEV_BUILD_WORLS_ONLY", cause its 100% reproducible commit
