[9.x] Add dontIncludeSource to CliDumper and HtmlDumper

[innocenzi]

This pull request adds a preventDumpingSource static method to Illuminate\Foundation\Concerns\ResolvesDumpSource, effectively affecting Illuminate\Foundation\Console\CliDumper and Illuminate\Foundation\Http\HtmlDumper.

When called, this method prevents the dump and dd functions from displaying a comment with the source of the dump.

While the idea is very nice, in practice it has made dumps cumbersome to read and understand for me. Here is an example:

The functionality can already be disabled by calling HtmlDumper::resolveDumpSourceUsing(fn () => null), but I didn't found out until I dove into the code. The point of this pull request is to allow preventing the dump resolution in a cleaner and more accessible way:

// Before
HtmlDumper::resolveDumpSourceUsing(fn () => null);
CliDumper::resolveDumpSourceUsing(fn () => null);

// After
HtmlDumper::preventDumpingSource();
CliDumper::preventDumpingSource();
