[1.10] Ensure auto peer is created regardless of term init

[carlos-zamora]

Summary of the Pull Request

This patch accomplishes what #10971 does, but for the release-1.10 branch. Some things couldn't be carried over because the TermControl split wasn't the complete (or in the same state as it is currently on main).

The bug was that Narrator would still read the content of the old tab/pane although a new tab/pane was introduced. This is caused by the automation peer not being created when XAML requests it. Normally, we would prevent the automation peer from being created if the terminal was not fully initialized.

This change allows the automation peer to be created regardless of the terminal being fully initialized by...

• ControlCore: initialize the _renderer in the ctor so that we can attach the UIA Engine before ControlCore::Initialize() is called (dependent on SwapChainPanel loading)

As a bonus, this also fixes a locking issue where logging would attempt to get the text range's text and lock twice. The locking fix is very similar to #10937.

Differences from #10971

This was prior to #10874. Thankfully, we don't need to worry about the padding because that bug was introduced as a part of #10051.

Validation Steps Performed

• New pane from key binding is announced by Narrator
• New tab from key binding is announced by Narrator
• Bounding rects are placed on the screen accurately (even when the padding changes)

✏️ Contributor please read this

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. 😉

🗜️ If you see a bunch of garbage

If it relates to a ...

well-formed pattern

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.

binary-ish string

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

File paths are Perl 5 Regular Expressions - you can test yours before committing to verify it will match your files.

^ 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).
