wpf: fix a handful of issues with the wpf control (#6983)

* send alt/F10 through the control
  We were not listening for WM_SYSKEY{UP,DOWN}
* extract the actual scancode during WM_CHAR, not the bitfield
  We were accidentally sending some of the additional keypress data in with
  the character event in Win32 Input Mode
* set default fg/bg to campbell
  The WPF control starts up in PowerShell blue even though it's not typically used
  in PowerShell blue.
* don't rely on the font to determine wideness
  This is a cross-port of #2928 to the WPF control
* deterministic shutdown
  In testing, I saw a handful of crashes on teardown because we were not shutting
  down the render thread properly.
* don't pass 10 for the font weight ...
  When Cascadia Code is set, it just looks silly.
* trigger render when selection is cleared, do it under lock

Fixes #6966.

(cherry picked from commit 76de2aedc2)

+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.
+
+:warning: 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/spell-check/dictionary/names.txt`.
+* ... APIs, you can add them to a file in `.github/actions/spell-check/dictionary/`.
+* ... just things you're using, please add them to an appropriate file in `.github/actions/spell-check/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/spell-check/patterns/`.
+
+See the `README.md` in each directory for more information.
+
+:microscope: 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](https://github.com/marketplace/actions/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. :wink:

+At present, the action that triggered this message will not show its :x: in this PR unless the branch is within this repository.

-# Comment management is handled through a secondary job, for details see:

-#
-# `jobs.comment-push` runs when a push is made to a repository and the `jobs.spelling` job needs to make a comment

-#   it needs `contents: write` in order to add a comment.
-#
-# `jobs.comment-pr` runs when a pull_request is made to a repository and the `jobs.spelling` job needs to make a comment
-#   or collapse a comment (in the case where it had previously made a comment and now no longer needs to show a comment)

-# Updating pull request branches is managed via comment handling.
-# For details, see: https://github.com/check-spelling/check-spelling/wiki/Feature:-Update-expect-list

-# These elements work together to make it happen:
-#
-# `on.issue_comment`
-#   This event listens to comments by users asking to update the metadata.
-#
-# `jobs.update`
-#   This job runs in response to an issue_comment and will push a new commit

-#
-# `with.experimental_apply_changes_via_bot`
-#   Tells the action to support and generate messages that enable it
-#   to make a commit to update the spelling metadata.

+        //
+        // After you wrote the numbers 0 to 6 into a queue of size 10, a typical state of the ring buffer might be:

+        // The remaining writable range on the other hand is [_producer, _consumer) = [7, 0).
+        // Wait, what? [7, 0)? How does that work? As all positions are modulo _capacity, 0 mod 10 is the same as 10 mod 10.
+        // If we only want to read forward in the buffer [7, 0) is thus the same as [7, 10).
+        //
+        // If we read 3 items from the queue the contents will be:

+        //          _consumer = 3      _producer = 7
+        //
+        // Now the writable range is still [_producer, _consumer), but it wraps around the end of the ring buffer.
+        // In this case arc will split the range in two and return each separately in acquire().
+        // The first returned range will be [_producer, _capacity) and the second [0, _consumer).
+        // The same logic applies if the readable range wraps around the end of the ring buffer.
+        //
+        // As these are symmetric, the logic for acquiring and releasing ranges is the same for both sides.
+        // The producer will acquire() and release() ranges with its own position as "mine" and the consumer's
+        // position as "theirs". These arguments are correspondingly flipped for the consumer.
+        //
+        // As part of the producer-consumer problem, the producer cannot write more values ahead of the

+        // determine positional differences smaller than the capacity. Due to that both producer and
