Implement PGO in pipelines for AMD64 architecture; supply training test scenarios
## References
- #3075 - Relevant to speed interests there and other linked issues.

* [x] New UIA Tests added and passed. Manual build runs also tested.
## Detailed Description of the Pull Request / Additional comments
- Creates a new pipeline run for creating instrumented binaries for Profile Guided Optimization (PGO).
- Creates a new suite of UIA tests on the full Windows Terminal app to run PGO training scenarios on instrumented binaries (and incidentally can be used to write other UIA tests later for the full Terminal app.)
- Creates a new NuGet artifact to store trained PGO databases (PGD files) at `Microsoft.Internal.Windows.Terminal.PGODatabase`
- Creates a new NuGet artifact to supply large-scale test content for automated tests at `Microsoft.Internal.Windows.Terminal.TestContent`
- Adjusts the release pipeline to run binaries in PGO optimized mode where content from PGO databases is leveraged at link time to optimize the final release build
The following binaries are trained:
- OpenConsole.exe
- WindowsTerminal.exe
- TerminalApp.dll
- TerminalConnection.dll
- Microsoft.Terminal.Control.dll
- Microsoft.Terminal.Remoting.dll
- Microsoft.Terminal.Settings.Editor.dll
- Microsoft.Terminal.Settings.Model.dll
In the future, adding `<PgoTarget>true</PgoTarget>` to a new `vcxproj` file will automatically enroll the DLL/EXE for PGO instrumentation and optimization going forward.
Two training test scenarios are implemented:
- Smoke test the Terminal by just opening it and typing a bit of text then exiting. (Should help focus on the standard launch path.)
- Optimize bulk text output by launching terminal, outputting `big.txt`, then exiting.
Additional scenarios can be contributed to the `WindowsTerminal_UIATests` project with the `[TestProperty("IsPGO", "true")]` annotation to add them to the suite of scenarios for PGO.
**NOTE:** There are currently no weights applied to the various test scenarios. We will revisit that in the future when/if necessary.
## Validation Steps Performed
- [x] - Training run completed at https://dev.azure.com/ms/terminal/_build?definitionId=492&_a=summary
- [x] - Optimization run completed locally (by forcing `PGOBuildMode` to `Optimize` on my local machine, manually retrieving the databases with NuGet, and building).
- [x] - Validated locally that x86 and ARM64 do not get trained and automatically skip optimization as databases are not present for them.
- [x] - Smoke tested optimized binary versus latest releases. `big.txt` output through CMD is ~11-12seconds prior to PGO and just over 8 seconds with PGO.
## Summary of the Pull Request
I came across a few build system bug fixes, which served their purpose now that VS 16.9 has been released.

Does what it says on the can.
This is a follow up to #9472. Now that we have a control .lib, we can add tests for it.
Unfortunately, the `TermControl` itself is a horrible mess. So this new unittest lib is empty for now. I'm working on actual tests as a part of #6842, but this PR is here to keep the diffs smaller.
Also, apparently `server.vcxproj` had the wrong GUID in it.

TIL that the `<None Include="Foo.def" />` line in our projects is
actually totally meaningless. The important line is the one that's in
`cppwinrt.build.pre.props`, where we declare
```xml
<ModuleDefinitionFile Condition="Exists('$(ProjectName).def')">$(ProjectName).def</ModuleDefinitionFile>
```
So if you change a project's name, and not the `.def` file, then the
linker will just _not use the `.def` file at all_.
More importantly, this seemingly doesn't matter in debug builds. In a
Debug build, the linker will happily still include `WINRT_CanUnloadNow`
and `WINRT_GetActivationFactory` in the exports from the dll, even
without the `.def`. But in a Release build, the linker is much more
agressive about pruning symbols that aren't referenced, and without
those two, NONE of the symbols are eventually referenced.
This PR fixes `Microsoft.Terminal.Control` by renaming the `.def`, and
makes it marginally harder for someone to make the same mistake in the
future.

**BE NOT AFRAID**. I know that there's 107 files in this PR, but almost
all of it is just find/replacing `TerminalControl` with `Control`.
This is the start of the work to move TermControl into multiple pieces,
for #5000. The PR starts this work by:
* Splits `TerminalControl` into separate lib and dll projects. We'll
want control tests in the future, and for that, we'll need a lib.
* Moves `ICoreSettings` back into the `Microsoft.Terminal.Core`
namespace. We'll have other types in there soon too.
* I could not tell you why this works suddenly. New VS versions? New
cppwinrt version? Maybe we're just better at dealing with mdmerge
bugs these days.
* RENAMES `Microsoft.Terminal.TerminalControl` to
`Microsoft.Terminal.Control`. This touches pretty much every file in
the sln. Sorry about that (not sorry).
An upcoming PR will move much of the logic in TermControl into a new
`ControlCore` class that we'll add in `Microsoft.Terminal.Core`.
`ControlCore` will then be unittest-able in the
`UnitTests_TerminalCore`, which will help prevent regressions like #9455
## Detailed Description of the Pull Request / Additional comments
You're really gonna want to clean the sln first, then merge this into
your branch, then rebuild. It's very likely that old winmds will get
left behind. If you see something like
```
Error MDM2007 Cannot create type
Microsoft.Terminal.TerminalControl.KeyModifiers in read-only metadata
file Microsoft.Terminal.TerminalControl.
```
then that's what happened to you.
