RFR: 8306580: Propagate CDS dumping errors instead of directly exiting the VM [v2]

[Matias Saavedra Silva]

> Currently, when CDS dumping run into an unrecoverable error (e.g., file I/O error, out of memory), it calls MetaspaceShared::unrecoverable_writing_error(), which directly exits the VM.  Some of these errors can be propagated to the caller for a normal exit. 
> 
> This change introduces `MetaspaceShared::writing_error()` to report errors without exiting the VM. The function `MetaspaceShared::unrecoverable_writing_error()` now should only be used for errors that require the VM to exit. Verifier with tier1-5 tests.
