feat: Add tasks for upload NDK symbol files to Datadog

[fuzzybinary]

What does this PR do?

This adds tasks for each variant, uploadNdkSymbolFiles{Variant} to upload symbols from native artifacts to Datadog. It utilizes similar logic from DdMappingFileUpload but encapsulates it into DdFileUploadTask. This logic is duplicated for now but we should probably refactor DdMappingFileUpload to use the DdFileUploadTask base class at some point.

NDK Symbol files have the key ndk_symbol_file, type ndk_symbol_file, and retain their original file name when uploading. The architecture of the symbol file is encoded into the "additional info" map when uploading.

Resolved most of the comments -- I still need to do the functional tests so I'll jump on that next.
