Fixes https://github.com/microsoft/playwright/issues/30160
### Description:
This pull request introduces the ability to specify custom locations for
test steps in Playwright. By enabling the provision of arbitrary
locations to the test.step method, it resolves the limitation where
helper methods obfuscate the original call site, providing more accurate
and meaningful location data in test reports.
### Motivation:
To enhance the utility and clarity of test reports in Playwright.
Specifically, it addresses the need to trace test steps back to their
precise location in the code, which is especially important when steps
are abstracted in helper functions. This feature is crucial for
maintaining accurate documentation and facilitating debugging processes.
### Changes:
Added functionality to pass a custom location object to test.step.
### Expected Outcome:
This PR is expected to significantly improve the precision and
usefulness of diagnostic data in test reports by allowing specific
locations within helper functions to be accurately documented. It
facilitates better tracking of test executions and simplifies the
debugging process, making it easier for developers to understand and
address issues within complex tests.

**Code Check**
I conducted tests on this new feature by integrating it into some
existing test codes, and it worked well. I will attach the code used for
testing and a screenshot showing the successful outcome.

Closes https://github.com/microsoft/playwright/issues/32578.
Adds a buffer mode that can be toggled by pressing <kbd>b</kbd>. When
engaged, changed test files are collected and shown on screen. The test
run is then kicked off by pressing <kbd>Enter</kbd>.
This changes the signal to start a test run from <kbd>Cmd+s</kbd> to a
<kbd>Enter</kbd> press in the test terminal. It should help users with
auto-save and make it easier to run on long-running tests. It feels very
similar to running `npx playwright test`, but without having to write a
filter.

Changes `expect.extend` behaviour so that it doesn't mutate the global
instance and behaves closer to what users expect. This is formally a
breaking change, and I had to remove a test that asserts the breaking
behaviour.
TODO:
- [x] decide wether this is a separate method or a flag for
`expect.extend`
- [x] figure out if we need to change docs
We now hopefully align with `moduleResolution: bundler` tsconfig option,
allowing directory imports in every scenario, and allowing proper module
imports when not going through the type mapping.
This regressed in #32078. Fixes#32480, fixes#31811.
Instead of plumbing it through a custom unspecified config field, make
it a part of plugin interface.
Additionally, use task runner for starting/stopping dev server.
After API review we decided to revert it:
* VSCode extension and UI mode users already get the (runtime) error if
the tag is not prefixed
* The typescript error message is not very nice
* The type change would break those clients that generate tests with
tags passed as string
This reverts commit 90e7b9ebac.
Closes https://github.com/microsoft/playwright/issues/32076.
This PR rewrites `watchMode.ts` to use `TestServer` under the hood. It's
essentially a complete rewrite, so don't pay too much attention on the
old implementation. Note that there's no changes to tests, so all
behaviour we have specced out there still works.
To make this work without a superfluous WebSocket connection, I had to
refactor `TestServerConnection` a little. Originally, I pulled this into
a [separate PR](https://github.com/microsoft/playwright/pull/32132), but
then realised how small the refactoring is. So it's in this PR now. Let
me know if you'd like to land it separately.
The `'should support custom matchers'` test asserts that the
functionality works, but it was a type error. This PR updates the types
so that it's allowed.
