All packages, except for `cmd` and `internal`, have been moved into a new `v1` root package.
Old packages are kept for backwards-compatibility reasons. All contained code is replaced with simple type aliases and proxy functions to `v1` implementations.
Old packages default to the Rego v0 syntax, new `v1` packages default to the Rego v1 syntax.

This commit includes evaluator support for an opt-in, non-deterministic
builtins caching system, designed to help with future replay of decision
logs.
The cache allows early-exit in the evaluator if the builtin is
non-deterministic, and has already cached a result. Since the cache can
be pre-populated by `rego` module users, this should make offline policy
testing and future work around decision replay more straightforward.

Adding host allow-listing based on the allow_net capability in the http.send()- and
net.lookup_ip_addr() built-in functions when running the eval command.

This follows the same approach as the wasm feature: by default, importers
of
github.com/open-policy-agent/opa/rego
github.com/open-policy-agent/opa/topdown
will not get a transitive dependency on the otel libraries.
In terms of functionality, nothing changes for the server and runtime.

This commit plumbs the print hook through to the wasm runtime so that
print calls are enabled when the wasm target is on. This commit also
updates the planner and compiler to support calls to void
functions--previously, the planner and wasm backend assumed that
functions returned values so they would perform checks for defined
values, however, with void functions, those checks must be suppressed.

Users of OPA as a library are concerned about big binary blobs in their vendor/
directories. Even more so if they don't use them. This is the case for anyone
using OPA as library, but not using the wasm-backed evaluation feature.
With this change, importers of any packages other than `server` and `cmd`
will have to explicitly opt-in to using wasm evaluation features by having an
underscore import somewhere:
import _ "github.com/open-policy-agent/opa/features/wasm"
Fixes#3545.
