refactor[react-devtools/tests]: use registered marks instead of cleared in tests (facebook#29929)

## Summary
This is the pre-requisite for
facebook#29231.

Current implementation of profiling hooks is only using
`performance.mark` and then makes `performance.clearMarks` call right
after it to free the memory. We've been relying on this assumption in
the tests that every mark is cleared by the time we check something.

facebook#29231 adds `performance.measure`
calls and the `start` mark is not cleared until the corresponding `stop`
one is registered, and then they are cleared together.

## How did you test this change?
To test against React from source:
```
yarn test --build --project=devtools -r=experimental --ci
```

To test against React 18:
```
./scripts/circleci/download_devtools_regression_build.js 18.0 --replaceBuild
node ./scripts/jest/jest-cli.js --build --project devtools --release-channel=experimental --reactVersion 18.0 --ci
```
