This change introduces an option to enable runtime assertions to catch
unintentional pdata mutations in components that are claimed as
non-mutating pdata. Without these assertions, runtime errors may still
occur, but thrown by unrelated components, making it very difficult to
troubleshoot.
For now, this doesn't change the default behavior. It just introduces a
new method on `[Metrics/Traces|Logs].Shared()` that returns pdata marked
as shared. The method will be applied to fan-out consumers in the next
PR.
Later, if we want to remove the need of `MutatesData` capability, we can
introduce another method `[Metrics/Traces|Logs].Exclusive()` which
returns a copy of the pdata if it's shared.
This change unblocks the 1.0 release by implementing the original
solution proposed by @bogdandrutu in
https://github.com/open-telemetry/opentelemetry-collector/issues/6794.
Going forward, we may introduce a copy-on-write solution that doesn't
require the runtime assertions. That will likely be part of the 2.0
release.
