build: statically link a subset of libraries

Now that Windows supports static link (to a certain extent), this
strategically statically links some of the internal libraries of Swift
Package manager.  This set was determined empirically, and was shown to
have a size benefit (beyond just reducing the distributed file count).

Before:
  273,408 Basics.dll
  543,232 Build.dll
3,083,776 Commands.dll
  187,904 LLBuildManifest.dll
  994,304 PackageCollections.dll
  168,960 PackageCollectionsModel.dll
  892,928 PackageCollectionsSigning.dll
   74,240 PackageFingerprint.dll
  818,176 PackageGraph.dll
  591,872 PackageLoading.dll
  776,704 PackageModel.dll
  220,672 PackageRegistry.dll
  181,248 SourceControl.dll
  560,640 SPMBuildCore.dll
   44,544 SPMLLBuild.dll
1,037,312 Workspace.dll
  587,776 XCBuildSupport.dll
  310,272 Xcodeproj.dll

   22,016 swift-build.exe
   24,576 swift-package.exe
   22,016 swift-run.exe
   22,016 swift-test.exe
11,438,592 bytes

After:
  273,408 Basics.dll
  662,528 Build.dll
5,531,136 Commands.dll
  817,664 PackageGraph.dll
  591,872 PackageLoading.dll
  776,704 PackageModel.dll
  560,640 SPMBuildCore.dll
1,355,264 Workspace.dll

   20,992 swift-build.exe
   23,552 swift-package.exe
   20,992 swift-run.exe
   20,992 swift-test.exe
10,655,744 bytes

This saves ~768KiB.

This additionally helps save ~1KiB from sourcekit-lsp after
SourceKit-LSP transitions to static linking.

Statically linking all the content in the repository causes the SPM
distribution to balloon 250% to ~25MiB and causes SourceKit-LSP to
balloon 300% to ~7MiB.

While it would be nice to statically link in Build into the Commands
(which saves ~100 KiB), it results in an overall bloat due to SK-LSP
increasing by ~300 KiB.
