Remove .NET Framework remarks (System.Diagnostics)

[gewarren]

.NET Framework API ref has moved to its own repo (https://github.com/dotnet/dotnetfw-api-docs), so we can clean up .NET Framework remarks, exceptions, and code examples out of this repo. Contributes to #12513.

Removes remarks related to:

• .NET Framework versions
• Code-access security
• Configuring apps via app.config file
• App domains

Also removes repetitive detailed info about enabling tracing.

Pull request overview

This PR updates the .NET API reference XML docs in System.Diagnostics* to remove .NET Framework-specific remarks (CAS, app.config configuration examples, AppDomain-era notes, and framework-only guidance), aligning this repo with the split of .NET Framework reference docs into dotnetfw-api-docs.

Changes:

• Removed .NET Framework-specific configuration-file guidance and other legacy remarks across tracing/debugging types.
• Simplified and modernized remarks/notes (including some wording and formatting updates to tables and markdown).
• Trimmed .NET Framework/CAS-related cross-references and repeated guidance in performance counter and event log docs.

• The sentence ends without punctuation. Add a period to keep the surrounding remarks grammatically consistent.

• There’s a missing space before the inline code span: “in atry/catch block” should be “in a try/catch block”.

> This type implements the <xref:System.IDisposable> interface. When you have finished using the type, you should dispose of it either directly or indirectly. To dispose of the type directly, call its <xref:System.IDisposable.Dispose*> method in a`try`/`catch` block. To dispose of it indirectly, use a language construct such as `using` in C#.
