Convert trivial scalar properties to auto-properties

Scalar value properties that merely forwarded to a private backing field
(IsAsync, Operator and the operator-type enums, Format, ClassType, Variance,
ParameterModifier, the parameter bool flags, and similar) become
auto-properties, formatted on a single line. Behavior is identical;
PrimitiveExpression's constructor sets the property instead of the dropped
field.
