android: create and upload debug symbols #15210
Description
What is the issue?
one of the top crashes on Play Console does not have a useful stack trace because we don't have debug symbols uploaded:

We are building our native library using -w to omit the DWARF symbol table from the final binary; this reduces the app size (by about 4MB on my debug build). We can create a symbols file by producing an unstripped version and a stripped version so that we create the debug symbols file, upload the stripped version so we aren't increasing app size, and use Google Play Developer API to upload the native symbols file.
