Run some MediaApp integration tests with guest and incognito profiles.

The AppService presents itself to the system differently in these
profile configurations, which has resulted in subtle crashes.

This CL configures SystemWebAppManagerBrowserTest with a third gtest
parameter type. It "defaults" to TestProfileType::kRegular and
establishes a way for system apps to neatly specify a set of their
tests that should have coverage for all profile types.

Bespoke tests for the HelpApp are migrated to this setup, and a subset
of pertinent MediaApp tests are parameterised for profiles.

Verified the desired coverage is satisfied by commenting out code
in web_file_tasks.cc that fixed things that have crashed in the past.
E.g. Unconditionally doing `profile = profile->GetOriginalProfile()`
causes 6 of the guest mode tests to crash, and omitting that completely
causes DCHECK(..IsAppServiceAvailableForProfile) to fail for the
incognito tests.

Logo Chromium

Chromium is an open-source browser project that aims to build a safer, faster, and more stable way for all users to experience the web.

The project's web site is https://www.chromium.org.

Documentation in the source is rooted in docs/README.md.

Learn how to Get Around the Chromium Source Code Directory Structure .

For historical reasons, there are some small top level directories. Now the guidance is that new top level directories are for product (e.g. Chrome, Android WebView, Ash). Even if these products have multiple executables, the code should be in subdirectories of the product.
