Enable Windows Arm64

[tsmarvin]

PR Summary

• Make LoadAssemblyInPsesLoadContext an Instance method instead of static to fix a crash on windows arm64.
• Add .vs directory to git ignore.
  • I realize this repo is primarily related to vscode, but I did open the solution in visual studio and wanted to ensure I didnt accidentally commit my state files.
• Remove unnecessary extra word in extension comment.

PR Context

I am experiencing crashes in the PSES internal host on Windows 11 arm64 (the qualcomm devkit). Here is an error log captured while print debugging showing the error:

I looked through the codebase but unfortunately I wasn't able to figure out where this specific method instance was being accessed from in order to have it search for the static method.

This, along with this pr, resolves the issues I'm experiencing and enables me to use the PowerShell extension for code formatting.

Hi, we reviewed this in triage today and are trying to ascertain what is calling LoadAssemblyInPsesLoadContext as an instance method such that this problem occurs. Can you give us more environment details? In our code, it's only referenced as the definition (as it's the public API available). Based on the callstack you provided, it seems to be something specifically in your profile. We also checked EditorServicesCommandSuite and it's not using it, so we're not sure what's calling it in your logs.

I will attempt to make time to get you this information tonight.

Unfortunately, if I can't get to it tonight I'll be traveling and away from my arm devkit for a week so it'll otherwise have to wait.
