Move sarif-parser.test.ts from no-workspace to unit-tests

I'm not sure why these tests were in the no-workspace suite. The code they test is in extensions/ql-vscode/src/common/ and has no vscode dependencies.

I've moved the test sarif data files from test/vscode-tests/no-workspace/data/sarif to test/data/sarif. I think this is a more suitable shared location for the test data.
We had tests in no-workspace (moved to unit-tests in this PR), activated-workspace, and react view tests. Since there's no one suitable suite to put the data, I think at the top level of the test directory makes most sense.
