Merge release/dev17.3 to main-vs-deps

[allisonchou]

Ideally #60429 should merge before this does.
After this, we should be able to delete release/dev17.3

A VB stack depth test is failing here. Maybe because we recently added a fix to actually run 64-bit tests in 64-bit mode? cc @jaredpar

Expected:
Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16),
Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16),
Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16)
Actual:
Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16),
Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16)
Diff:
Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16)
Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16)
-->     Diagnostic(ERRID.ERR_TooLongOrComplexExpression, "a").WithLocation(7, 16)
Expected: True
Actual:   False

I'm assuming the plan is to disable the test and add a tracking issue?
