fix: TOC items order issue

[filzrev]

This PR intended to fix issue #10332

Background
When using Globalization Invariant Mode. string is sorted with ordinal orders.
And it will cause some order problems, which seems not to be natural orders.

What's changed in this PR

1. Add SymbolStringComparer.cs

Add custom StringComparer that sort ASCII chars.
It's similar to StringComparer.InvariantCulture's order but have following differences.

• Non ASCII chars are sorted with ordinal order.
• Non-printable chars are compared. (built-in string comparer seems ignoring these chars)
• Char orders of ',' and ')' are inverted. (To handle .NET overloaded method parameter orders)

2. Modify YamlViewModelExtensions.cs

Modify toc /enum items sort logics to use custom SymbolStringComparer.

3. Add test class to that contains test for Issue10332

Confirmed generated web site symbols are ordered as expected.
And enumSortOrder:alphabetic behavior is confirmed by modifying seed/docfx.json manually.

Additional apply formatter to Class1.cs file content.

4. Update snapshot files with snapshot.yml
