Fixes #8882

1. Add IsChecked flag for IIncrementExpression and ICompoundAssignmentExpression
2. Add back VB specific binary operator kinds
3. Add more unit tests and fix baselines of existing tests

This implements a bunch of changes to the IOperation representation for binary operator, unary operator and increment expressions.

1. #8834: Simplify `UnaryOperatorKind` to only contain the operator kind values instead of a matrix of operator and operand kinds.
2. #8835: Simplify `BinaryOperatorKind` in similar manner as above.
3. #8825: Add `IUnaryOperatorExpression.IsChecked` flag. Cyrus has already added the `IUnaryOperatorExpression.IsLifted` flag.
4. #8846: Add `IBinaryOperatorExpression.IsChecked` and `IBinaryOperatorExpression.IsCompareText` flags Cyrus has already added the `IBinaryOperatorExpression.IsLifted` flag.
5. #21283: Add `IIncrementExpression.IsDecrement` and `IIncrementExpression.IsPostfix` flags and remove PostFix/Prefix Increment/Decrement from `UnaryOperatorKind` enum.

This change also fixes #8848 and #8843 as the matrix operation kind enums no longer exist.

* Expose if a Binary/Unary operator was 'Lifted' at the IExpression level.

* Update public API.

* Share computed value.

* Remove unnecessary extension.

* Update test code.

* Remove extension method.

* Fixup tests.

* Fixup tests.

* Fixup tests.

* Fix instances of Invalid operations with nullable

* Compound assignments also need to state if they're lifted.

* Move tests.

* Move tests.

* Move tests.

* Simplify comment.

* Case things consistently.

* Use F instead of Foo.  Because Foo is bad.
