[release/8.0] Backport improvements to Http and Ssl stress tests

[MihaZupan]

Closes #122267

Customer Impact

• Found internally

Our HTTP and SSL stress tests are experiencing intermittent build failures.
This change backports stress infra & testing improvements we've made since the 8.0 release, which also resolves the build failures.

Regression

• No

Infra update.

Testing

CI stress runs.

Risk

Low. Test only change.

@MihaZupan - the code complete for January servicing for 8.0.x and 9.0.x is December 5th in case you were planning to get this in for Jan.

LGTM, thanks!

Pull request overview

This PR backports stress test infrastructure improvements from the main branch to release/8.0, updating both HttpStress and SslStress projects to use a common, shared infrastructure. The key change specific to 8.0 is that TrackUnobservedExceptions is disabled by default, as noted in the PR description, since many product fixes have been made since 8.0 that would make this feature very noisy in the release branch.

Key Changes

• Consolidates duplicate stress test infrastructure code into a common location (src/libraries/Common/tests/System/Net/StressTests/)
• Updates Docker configurations to use correct SDK versions (8.0 instead of 6.0/7.0)
• Standardizes environment variable names (STRESS_ARGS instead of HTTPSTRESS_ARGS/SSLSTRESS_ARGS)
• Adds new entrypoint scripts for improved dump collection and error handling
• Upgrades System.CommandLine package from experimental version to beta5
• Adds connection initialization logic to SslStress client to handle container startup race conditions
