Create a Docker image containing the QNX development environment

[linguini1]

This GitHub repository has several workflows set up; however it's crucial that we ensure our codebase can be fully built within the QNX development environment. This includes:

• No compilation errors
• No compilation warnings
• No files missed by the Makefiles
• Use manual is included in binary
• All builds can be fully made

Having a workflow that checks all these things before PRs get merged would be incredibly helpful, since we don't want any one PR to be able to break the codebase. This could be hard to track down.

Because we don't have a Docker image containing all the QNX development tools, we are using an honour system to make sure developers check that their code compiles before submitting it as a PR. This shouldn't be a long-term solution.

This document contains information about how to set up the QNX Software Development Platform (SDP) as a Docker image. We will have to make our own. Note that you must be logged in to your myQNX account to view the document.
