Fix compilation errors due to insufficient compiler safety (bug#63288)

Browse source 
The default safety level is 1.  Restoring the default safety level to
1 after it was temporarily 0 should reset byte-compile-delete-errors
to nil, its default level.  Failing to do that resulted in
miscompilation of code in highly-parallel builds.

* lisp/emacs-lisp/cl-macs.el (cl--do-proclaim): Change
'byte-compile-delete-errors' to become t only at 'safety' level 0, not
levels 1 or 2.
