Broken out of https://github.com/microsoft/playwright/pull/31727 as per
@dgozman's
[request](https://github.com/microsoft/playwright/pull/31727#discussion_r1685793229).
The PR goal is to remove the `suite` argument from the Component
testing's Vite Plugin. `suite` is used to enrich Vite's dependency graph
with information about dependencies between test suites and helper
files. It essentially merges the Vite graph with the
`compilationCache.ts > fileDependencies` graph, and then writes the
result back into `compilationCache.ts > externalDependencies`.
By refactoring this to make the connection on the reading end in
`collectAffectedTestFiles`, we can drop the `suite` parameter.
We didn't yet have a test that depended on the dependency graph being
connected correctly between `fileDependencies` and
`externalDepedencies`, so I've [extended an existing
test](53a539938b)
to capture that.
Previously, only the "actual" attachment was created, pointing to the
file in `test-results`. Now, the "expected" attachment pointing to the
file in `__screenshots__` is also created. This will help any reporters
that would like to know the "expected" path, for example to do a manual
accept/decline of the baseline.
Fixes#30693.
... unless an array of file-system-friendly parts is provided.
Motivation: attachment name is used as a file system path when
downloading attachments, so we keep them fs-friendly.

When used in a terminal, the `list` reporter prints out information
about test steps to help debugging. In non-TTY environments like GitHub
Actions, currently it doesn't.
This PR changes that, so that in non-TTY environments you'll see the
"step end" messages appearing, but not the "step begin" messages. This
is a good middleground, because it helps the user understand test
progress, without being too verbose.
Closes https://github.com/microsoft/playwright/issues/31674
Retaining traces in the following scenarios:
- browser crash;
- manual `browser.close()`;
- implicit `browser.close()` from the `browser` fixture upon test end.
This does not affect the library, where `browser.close()` will not
retain the trace and will close the browser as fast as possible.

Historically, this plugin was important to translate dynamic imports
into require calls so that we can intercept them and transpile.
This is not needed anymore with ESM loader enabled by default, so we can
avoid this transformation and support dynamic imports of ESM-only
packages/files.
Fixes#17075, fixes#23255, fixes#31140, references #23662.
When merging blob reports test ids are patched to make sure there is no
collision when merging reports that might have overlapping test ids.
However, even if you were merging reports that had no overlapping ids,
all test ids will be modified, which is an undesirable side effect.
This PR only modify test ids when the same test id has already been used
in a previous blob report.

This change is also part of
https://github.com/microsoft/playwright/pull/30962
The spirit of this change is reverting #23153. Since that time, we have
moved tracing and `artifactsDir` lifetime into the test runner, so the
reason for revert is mitigated.
Fixes#30287, fixes#30718, fixes#30959.
This includes two major changes:
- reuse `SerializedFS` for live test runner tracing;
- merge scheduled `appendFile` operations into a single `fs` call.
In some cases, this improves performance of UI mode by 61% and
performance of `trace: on` mode by 38%. Note that performance
improvement on the average test will not be as noticeable.
