These tests had several issues. The fixes are aimed to reduce flakiness
and remove invalid configurations where tests are not providing any
value. Some of the issues include:
* some tests interferered with each other causing a 18% flakiness rate
in chrome: they used a common file system that ended up being shared
in a single browser instance. This is why some tests failed when they
find a file exists before it was created [1].
* some tests were not properly using async_helper/async_minitest, so
they may complete before they finish executing
* DDC no longer supports these APIs due to
https://github.com/dart-lang/sdk/issues/53864. We don't intend to fix
those issues, so there is no purpose in running these tests in DDC at this
time.
