[ruby/psych] Introduce `Psych.unsafe_load`

2021-05-17T02:20:45+00:00

In future versions of Psych, the `load` method will be mostly the same
as the `safe_load` method.  In other words, the `load` method won't
allow arbitrary object deserialization (which can be used to escalate to
an RCE).  People that need to load *trusted* documents can use the
`unsafe_load` method.

This commit introduces the `unsafe_load` method so that people can
incrementally upgrade.  For example, if they try to upgrade to 4.0.0 and
something breaks, they can downgrade, audit callsites, change to
`safe_load` or `unsafe_load` as required, and then upgrade to 4.0.0
smoothly.

Config is Ractor-local.

Benchmarking reveals that using `Ractor.local_storage` for storing cache
is similar to accessing a constant (~15% slower).
