There is some risk to this change. The first is that I made a mistake. The
other is that one of the APIs that doesn't currently return an error changes
in the future.
Follows up on https://github.com/lightpanda-io/browser/pull/994 and replaces
the jsRunner with a new page.navigation-based test runner.
Currently only implemented for the Window tests, looking for feedback and
converting every existing test will take time - so for a while, newRunner (to be
renamed) will sit side-by-side with jsRunner.
In addition to the benefits outlined in 994, largely around code simplicity and
putting more of the actual code under tests, I think our WebAPI tests
particularly benefit from:
1 - No need to recompile when modifying the html tests
2 - Much better assertions, e.g. you can assert that something is actually an
array, not just a string representation of an array
3 - Ability to test some edge cases (e.g. dynamic script loading)
I've put some effort into testing.js to make sure that, if the encapsulating
zig test passes, it's because it actually passed, not because it didn't run.
For the time being, console tests are removed. I think it's more useful to have
access to the console within tests, than it is to test the console (which is
just a wrapper around log, which is both tested and heavily used).
There's a flaky performance test that I wanted to fix (1). This led to a couple
changes.
1 - Add timestamp() and milliTimestamp() to datetime.zig. Reduce some code
duplication and use better clock_ids where available
2 - Change Performance API to use milliTimestamp and store a u64 instead of a
f64. While the spec says a float, Firefox deals with u64 and implicit
conversion is always available. Makes our APIs simpler.

Test speed has been improved only slightly by tweaking a 2-second running tests.
Build has been improved by:
1 - moving logFunctionCallError out of js.Caller and to a standalone function
2 - removing some non-generic code from the generic portions of the logger
Caller.getter and Caller.setter have been removed in favor or calling
Caller.method. This wasn't previously possible - prior to our v8 upgrade, they
had different signatures.
Also removed a largely unused parser/str.zig file.
1 - Add a custom console.lp function to make our debug logs stand out from
script logs.
2 - In some cases, significantly improve how JavaScript values are serialized
in debug logs and in console.log.
1 - Make log_level a runtime option (not a build-time)
2 - Make log_format a runtime option
3 - In Debug mode, allow for log scope filtering
Improve the general usability of scopes. Previously, the scope was more or less
based on the file that the log was in. Now they are more logically grouped.
Consider the case where you want to silence HTTP request information, previously
you'd have to filter out the `page`, `xhr` and `http_client` scopes, but that
would also elimiate other page, xhr and http_client logs. Now, you can just
filter out the `http` scope.
Outputs in logfmt in release and a "pretty" print in debug mode. The format
along with the log level will become arguments to the binary at some point in
the future.
In debug mode, it has a more user-friendly output:
level | the log messge | ms since last message | key=value key=value
In release mode, it logs using logfmt, which is supported by most log
ingestion frameworks.
Not being used anywhere right now, keeping this PR small with no impact on
existing code.
