Hacky support for building plugin dependencies for the host. This is achieved by creating a second build operation with altered build parameters and individually building dependencies using that build operation, somewhat similar to how command plugins operate.

When cross-compiling, SwiftPM plugins and their dependencies run on the host and so must be compiled for the host OS and architecture, not the cross-compiled target OS and architecture. SwiftPM will correctly compile a command plugin for the host but if the plugin depends on an executable SwiftPM will cross-compile the executable for the target, so the plugin will not be able to run it: error: Error Domain=NSPOSIXErrorDomain Code=8 "Exec format error" Command plugin dependencies are already handled specially in PluginCommand.run; this commit makes that special build step use the host toolchain instead of the target toolchain. swiftlang#6060 handled the equivalent problem for build tool plugins.
