Optimize TS generator, remove trailing whitespace from generated

[jonaro00]

Proposed changes

• I noticed that the TypeScript emitters (Clone, Serialize) do not care about the passed Diagnostics. The diagnostics take the most runtime. Therefore, I skip generating the diagnostics for those builds, which led to ~4.5s faster builds 😄. Since pretty much all other npm scripts in turn run the generate-typescript script, their build times also benefit from this speedup.
• General code improvements in files related to the above.
• Remove trailing whitespaces from the generated files.
• Minor test case logging fixes.
• Remove deprecated fields in .vscode launch configurations. Set default line ending to not save files as CRLF and mess with git.
