Adding ReadConsoleInput to the API.

[chhackett]

Description

There are some new data types in Console/Internal.hsc to support the ReadConsoleInput API:
KEY_EVENT_RECORD
MOUSE_EVENT_RECORD
WINDOW_BUFFER_SIZE_RECORD
MENU_EVENT_RECORD
FOCUS_EVENT_RECORD
INPUT_RECORD

The exported function readConsoleInput is also added.

Motivation and Context

There are several apps that have used the ReadConsoleInput Win32 API method. This
leads to a bit of code duplication. Since these apps already use the Win32 library, it
just makes sense to consolidate that code into one place.

Looks like one of the CI tests is failing on several PRs. Here's the error:
ERROR: The running command stopped because the preference variable "ErrorActionPreference" or common parameter is set to Stop: Cannot find path 'C:\WORK\s\appveyor\AppData\Roaming\cabal\config' because it does not exist.
Environment Vars (like PATH) have changed. Close/reopen your shell to
see the changes (or in powershell/cmd.exe just type refreshenv).
The install of cabal was NOT successful.
Error while running 'C:\ProgramData\chocolatey\lib\cabal\tools\chocolateyInstall.ps1'.
See log for details.

Yeah the 32-bit CI is broken, don't worry about that. Thanks for the PR!

This should use the WINDOWS_CCONV macro instead of ccall but other than that looks good!

[chhackett]

OK, took care of that.

Thanks!
