On Unix systems, fallback to plaintext manipulation instead of using the DPAPI which is not available.
## PR Context
Currently, existing scripts that use SecureString cmdlets fail with an error complaining about crypt32.dll not being available. This change allows these cmdlets to be used, but there is no encryption of the string.
.Net already [states](https://docs.microsoft.com/en-us/dotnet/api/system.security.securestring?view=netcore-2.1#remarks) that the contents of a SecureString are not encrypted on .Net Core.

By not doing excessive amounts of extra work, formatting can be sped up quite significantly (about 8x faster).
The main change comes from adding new, more efficient, primitive to query an object for the existence of an instance member.
The formatting system has been checking for if an object has properties other than some decorated properties added by PS remoting, and it doesn't this by retrieving all properties which results in heavy allocations and wasted cycles.
By adding `GetFirstOrDefault` to `PSObject` and similar primitives to the underlying Adapters, we are able to return early, without having to get all properties back.
Improve type inference for foreach statement variables by:
Inferring strongly typed arrays from explicit array and array literal expressions when elements are of the same inferred type
Fix detection of foreach variable declaration. The previous logic was to check if the variable expression's start offset was after the end offset of the foreach statement, which will never be true in the body
Improve inference of what type the "Condition" of a foreach statement will enumerate as
Update the task-based async APIs added to PowerShell to not use the `aysnc/await` keywords, but to return a `Task` object directly.
There is nothing to continue on after the `Task.Factory.FromAsync` call in those methods, so there is not need to use `aysnc` and `await` keywords, which turns the method into a state machine class unnecessarily.
Here are the major changes:
- Add logic to skip checking for possible resource directories for the first set of sub directories from the top level.
- There was an additional skip if the folder is hidden, rather than doing an explicit attribute check, change the `EnumerationOption` to skip hidden folders.
- Since the `IsPossibleModuleDirectory()` helper now only checks to see if the name matches a culture, renamed to `IsPossibleResourceDirectory()`
- When getting the default modules, we don't search recursively into individual module folders, so removed additional check for possible resource directory.
Adds an optional -Depth parameter to the cmdlet which lets the user to specify a maximum depth allowed for deserialization, which will overwrite the default maximum of 1024.
`TypeBuilder.GetInterfaces()` returns only the interfaces that was explicitly passed to its constructor, so we need to flatten the interface hierarchy in order to properly support inherited interfaces.
This removes some of the last mentions of the AppVeyor name. Don't change the title, we don't want the word to appear in the CLs
Also problem: the last references are in the changelogs but I don't want to modify them without committee approval.
