RFR: 8294954: Remove superfluous ResourceMarks when using LogStream [v2]

[Johan Sjölen]

> Hi,
> 
> I went through all of the places where LogStreams are created and removed the unnecessary ResourceMarks. I also added a ResourceMark in one place, where it was needed because of a call to `::name_and_sig_as_C_string` and moved one to the smallest scope where it is used.

Johan Sjölen has updated the pull request incrementally with one additional commit since the last revision:

  Put back VM_Operation::evaluate ResourceMark
