* Remove NonPrivateXCTestMembersRule
I accidentally implemented this rule twice. So TestCaseAccessibilityRule
did the same thing but with a bit more behavior. This change deletes
NonPrivateXCTestMembersRule but also ports over the autocorrection from
it to TestCaseAccessibilityRule.
Current events have renewed the conversation in our community about the roles of terminology with racist connotations in our software. Many companies and developers are now taking appropriate steps to remove this terminology from their codebases and products. (e.g. [GitHub](https://twitter.com/natfriedman/status/1271253144442253312)) This small rule prevents the use of declarations that contain any of the terms: whitelist, blacklist, master, and slave. It may be appropriate to add more terms to this list now or in the future.
We were using this lock to guarantee a new ID for every file, but we can
get that benefit by using values that are guaranteed to be unique
without the need for locks, such as a UUID.
By using SourceKit's `index` request to index the entire source file,
we can avoid having to make `cursor-info` requests for every candidate
token in the file, which scales linearly with the number of candiate
tokens.
For the Yams project, this approach improved the total SwiftLint run
time by 4.6x: 7.9 down from 36.8s.
The SourceKit index response doesn't have everything we need to identify
declarations, so we still need to make some `cursor-info` requests,
mostly to detect overrides: protocol conformances and parent class
overrides.
This approach ends up finding more unused declarations because the index
contains more declared USRs than can be found by calling `cursor-info`
on candidate tokens in a file.

Update package versions
This allows custom rules to define an `excluded_match_kinds` array instead of listing out all but one or a few of the `SyntaxKind`s in `match_kinds`. Rules that include both `match_kinds` and `excluded_match_kinds` will be invalid, since there's not an obvious way to resolve the two without an arbitrary priority between them.
