macro_placement doesn't recognize MACRO's with CLASS RING as placeable
Describe the bug
macro_placement doesn't recognize MACRO's with CLASS RING.
macro_placement
[WARNING MPL-0100] No macros found.
iccad04 RISC2 testcase. After changing RING to BLOCK, macro_placement works. https://github.com/The-OpenROAD-Project/OpenROAD/issues/5284
In order to make the testcase fail again, change lef/risc2.lef.gz back to using RING.
MACRO tsyncram_512x32
CLASS RING ;
MACRO rf_128x22
CLASS RING ;
MACRO rf_8x32
CLASS RING ;
Expected Behavior
treat MACRO's with CLASS RING as macro's to be placed by the macro_placement
Environment

Features included (+) or not (-): +Charts +GPU +GUI +Python
To Reproduce
In order to make the testcase fail one has to change lef/risc2.lef.gz back to using RING.

I've never see a macro of class RING in any PDK we deal with so this is something new (or more likely very old). My guess is lots of things that deal with macros will not handle this case. I suggest for your purpose you just change these to type BLOCK as this isn't a production design. We can keep this open but as a low priority.
