           Summary: [REGRESSION]PropertyGrid: Value type properties with no
                    set accessor should display read-only

Screenshot

For instance, the ToolBarButton.Rectangle property[1] on MSFT is displayed
read-only (greyed) as are all the sub properties.  On Mono the property and
sub-properties are both displayed normal non-greyed (the sub-properties
actually in bold).  No edit is allowed to the property.  The sub-properties can
be edited, but any edits are discarded.
[1. On a item in the ToolBar.Buttons collection]

The property has no set accessor, (and has no attributes).  Since Rectangle is
a value type, calling any set property on the value returned by the get
accessor is pointless as.  it is a copy and this any edits are discarded. 
(Correct?)

Thus such properties should be displayed read-only.  This was correct in Mono
1.9.  See screenshot.  Repro with attached updated 'PG with many types' app,
see "NoSetter" category.
