RFR: 8369818: G1: Add missing region types in gc+heap=debug heap output [v2]

[Thomas Schatzl]

> Hi all,
> 
>   please review this update to the `gc+heap=debug` output to contain all region types (I do not know why it only showed eden and survivor).
> 
> This is also printed in other places (like `hs_err` files) and it is sometimes very interesting to know that e.g. there are humongous regions around.
> 
> It also makes the unit MB because KB is too unwieldy, and the minimum region size is 1 MB anyway.
> 
> Testing: local compilation, checking the log output
> 
> Thanks,
>   Thomas
