What does this PR do

This commit implements the file search extension for Windows platforms using the Windows Search functionality.

Something to note:

1. Searching by file content is not natively supported. Coco would search for all the columns (attributes/fields within the index) with this option:

        SearchBy::NameAndContents => {
            // Windows File Search does not support searching by file content.
            //
            // `CONTAINS('query_string')` would search all columns for `query_string`,
            // this is the closest solution we have.
            format!("((System.FileName LIKE '%{query_string}%') OR CONTAINS('{query_string}'))")
        }

2. Tests have been added, but they failed in our CI for unknown reasons so I disabled them:

// Skip these tests in our CI, they fail with the following error 
// "SQL is invalid: "0x80041820""
// 
// I have no idea about the underlying root cause
#[cfg(all(test, not(ci)))]
mod test {

3. The Windows Search index is not real-time and can return obsolete results. Opening the returned documents could fail if the chosen file has been deleted or moved.
