Detect forked pull request on AppVeyor CI

[bahmutov]

We have special logic to detect forked pull requests on CircleCI and run tests without recording even when the CI file says cypress run --record. (we do show a warning in the terminal)

I have noticed that we don't detect this situation on AppVeyor, see https://ci.appveyor.com/project/cypress-io/cypress-example-kitchensink/builds/24174895 for example

run-if npm run test:ci:record
Platform win32 is allowed
Arch ia32 is allowed
> [email protected] test:ci:record C:\projects\cypress-example-kitchensink
> run-p --race start:ci e2e:record
> [email protected] start:ci C:\projects\cypress-example-kitchensink
> http-server app -c-1 --silent
> [email protected] e2e:record C:\projects\cypress-example-kitchensink
> cypress run --record
You passed the --record flag but did not provide us your Record Key.
You can pass us your Record Key like this:
  cypress run --record --key <record_key>
You can also set the key as an environment variable with the name CYPRESS_RECORD_KEY.

[bahmutov]

we can check values of APPVEYOR_REPO_NAME and APPVEYOR_PULL_REQUEST_HEAD_REPO_NAME - if they are the same, this is internal PR. If they are different, then this is a forked pull request

[cypress-bot]

The code for this is done in cypress-io/cypress#4078, but has yet to be released.
We'll update this issue and reference the changelog when it's released.
