Update pipeline to produce zip with binaries + pdbs for addition to GitHub Releases page

[bbonaby]

📖 Description

PR makes our build pipeline produce a mxc-release-binaries.zip file that can be added to the github releases page on every release. The pipeline will now also produce pdbs and add it to the zip. This is a stop gap until we have symbol publishing, Although I think we'll keep doing this for folks who want easy access to the symbols.

Pull request overview

This PR updates the Azure Pipelines release flow to emit a single mxc-release-binaries.zip containing per-architecture MXC executables plus symbol files, intended for upload to GitHub Releases as a stopgap until symbol publishing is available.

Changes:

• Enables full release debuginfo in the Rust workspace so CI builds produce symbol artifacts (PDB/DWP).
• Extends per-target build artifacts to include symbol files alongside binaries.
• Adds a new packaging job to bundle all per-arch artifacts into mxc-release-binaries.zip, while stripping symbols from the npm SDK package.
