Disable the VT color quirk for pwsh and modern inbox powershell

[DHowett]

In #6810, we introduced a "quirk" for all known versions of PowerShell
that suppressed their requests for black background/gray foreground.
This was done to avoid an issue in PSReadline where it would paint
black bars all over the screen if the default background color wasn't
the same as the ANSI black color.

Years have passed since that quirk was introduced. The underlying bug
was fixed, and the fix was released broadly long ago. It's time for us
to remove the quirk... almost.

Terminal still runs on versions of Windows that ship a broken version of
PSReadline. We must maintain the quirk there -- the user can't do
anything about it, and we would make their experience worse if we
removed the quirk entirely.

PowerShell 7.0 also ships a broken version of PSReadline. It is still in
support for another 6 months, but updates have been available for some
time. We can encourage users to update.

Therefore, we only need the quirk for Windows PowerShell, and then only
for specific versions of Windows.

Inside Windows, we don't even need that: we're guaranteed to be built
alongside a fixed version of PowerShell!

Closes #6807

By default the command suggestion will generate a file named based on your commit. That's generally ok as long as you add the file to your commit. Someone can reorganize it later.

⚠️ The command is written for posix shells. You can copy the contents of each perl command excluding the outer ' marks and dropping any '"/"' quotation mark pairs into a file and then run perl file.pl from the root of the repository to run the code. Alternatively, you can manually insert the items...

If the listed items are:

• ... misspelled, then please correct them instead of using the command.
• ... names, please add them to .github/actions/spelling/allow/names.txt.
• ... APIs, you can add them to a file in .github/actions/spelling/allow/.
• ... just things you're using, please add them to an appropriate file in .github/actions/spelling/expect/.
• ... tokens you only need in one place and shouldn't generally be used, you can add an item in an appropriate file in .github/actions/spelling/patterns/.

See the README.md in each directory for more information.

🔬 You can test your commits without appending to a PR by creating a new branch with that extra change and pushing it to your fork. The check-spelling action will run in response to your push -- it doesn't require an open pull request. By using such a branch, you can limit the number of typos your peers see you make. 😉

See if there's a pattern that would match it.

If not, try writing one and adding it to a patterns/{file}.txt.

Patterns are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your lines.

Note that patterns can't match multiline strings.

Please add a file path to the excludes.txt file instead of just accepting the garbage.

^ refers to the file's path from the root of the repository, so ^README\.md$ would exclude README.md (on whichever branch you're using).

Discussion outcome: option 1 - DSAT and tell users to upgrade. Thanks!

[DHowett]

I also changed how ConsoleShimPolicy works because the way it was written was strange. A static in-class constructor that doesn't poke at its private boolean members, but calls a private constructor anyway? That just seems like too many steps. Instead of adding a third parameter, it seemed easier to just make the ctor exception-safe and move to accessing the members directly.

[DHowett]

fwiw it seems like it would be reasonable to not check if it's pwsh if it's cmd, but... eh. whatever. it was always this way.

[lhecker]

LGTM. If you don't mind you could also remove this line:

clientName.erase(std::find(clientName.begin(), clientName.end(), '\0'), clientName.end());

It got fixed a while ago in microsoft/wil#165

[DHowett]

OH DANG I HAD NO IDEA IT WAS FIXED
