Create targeting pack MSI installers (dotnet/core-setup#5114)

* Create targeting pack MSI

This change has the targeting pack pkgproj create an install layout based on the nupkg's data/ dir. That's picked up by the targeting pack installer project the same way it is for hostfxr and shared framework. In general, the targeting pack installer project is a copy of existing installers with very little changed.

In official builds, build the full platform manifest on win-x86, not just win-x64. Both platforms' installers need the full manifest.

* Change install dir "ref" => "packs"

* "Microsoft .NET Core Targeting Pack" branding

* Remove "netcoreapp" from MSI filename

The name "dotnet-targeting-pack" brings it in line with installer names like "dotnet-runtime" and "dotnet-host".

* Fix targeting pack powershell script: PR comments

I plan to remove this script entirely, but it might as well be a little cleaner while development is ongoing.

* Fix DependencyKey: Dotnet_CLI => Dotnet_Core

* Fix typo: GeneratedGui => GeneratedGuid

Simplify computation of oldest framework reference (dotnet/core-setup#5142)

Instead of passing the list of oldest references all the way down to the code which performs roll forwards, simply assign to it when we enumerate reerences for the first time.
The only difference is that in case of a failure the oldest reference will be filled while before it would not be fully up to date.

COM Activation host (dotnet/core-setup#4577)

* Add new comhost library for COM activation
 - Supports reading clsidmap as file or resource
 - Supports registration and unregistration of COM server

* Replace COREHOST_MAKE_DLL define with EXPORT_SHARED_API

* Convert CoreClr instance loading API from a flat C-style to a class API . This will make having multiple CoreClr instances in the same process easier in the future.

* Move internal execute* APIs to the fx_muxer.cpp compilation unit
Add initial/erroring implementation for get_com_activation_delegate() to fx_muxer_t.

* Extract coreclr property creations into a reusable class.

* Report process ID during test run.

* Remove the new corehost_ensure_load() export since the previous semantics
  of reinitializing hostpolicy were designed for testing.

* Fix P/Invoke signature for hostfxr_get_native_search_directories to define
  the calling convention and remove usage of StringBuilder.

* Properly propagate the host command on reinitialization
Remove additional uses of global variables where possible

* Don't add the COM server assembly to the TPA
Ensure the COM server assembly deps.json isn't added to the AppContext

Fix lookup of coreclr.dll in .deps.json to not rely on relative paths (dotnet/core-setup#5050)

The existing code expects the .deps.json record for coreclr.dll (and clrjit.dll) to have at least one directory separator, since that was always the case up until now.
With recent changes to targeting packs, these records are just file names, and the above logic breaks.

Fix the logic by lookup at the resolved absolute path, which is guaranteed to have a directory separator before the library name (we need the separator to match whole file names).

Added a test which validates the new scenario.

Fix the timestamp timezone in tracing in Windows (dotnet/core-setup#5049)

It seems that printing out timezone information for a tm structure on Windows always shows the local timezone, even if the tm is returned by gmtime.
The simplest fix seems to be to simply print out GMT always, after all gmtime always returns GMT time.
This also makes the output match Linux formating as Windows otherwise uses verbose zone names, while Linux uses abbreviations.

Fix registry access on legacy windows (dotnet/core-setup#5042)

The bug was that RRF_SUBKEY_WOW6432KEY is only supported on Win10. On legacy Windows it has no effect and 64bit registry is accessed.

The fix is to use RegOpenKeyEx which takes the access right parameter which can specify KEY_WOW64_32KEY. This makes 64bit app access the 32bit registry and this one is supported on anything above Windows 2000 (excluded).

The existing fwlink is now redirected to point to the Windows prereq page. Two new fwlinks were added to point to OSX and Linux pages.

Added simplistic tests for these changes.

Host UI errors (dotnet/core-setup#4844)

Implements reporting errors with message box for Windows GUI apps in apphost.

In apphost, if it's running as GUI, error writing will be redirected to a buffer. Upon exit, if the error buffer is not empty, it will be showed on screen as a message box.
The error writer is propagated from apphost to hostfxr and thus to hostpolicy.

This solves the problem that GUI apps which don't have console die silently without reporting any errors if there are issues during host execution.
