[processor/transform] Write log if truncation or limiting is performed

[TylerHelmuth]

Any functions in the transform processor that truncate or limit attributes should write out a log, following the specification. Currently there are 2 functions, truncate_all and limit that do this. Those functions, and any functions added in the future, should be able to write a log once per record on which the function was performed.

Additional context
Originated from comment in #9552. The functionality was not originally added as part of the truncate_all and limit PRs due to the lack of a logger in functions.go. I experimented with print statements, which probably could work, but I think using an actual zap.logger is the proper solution.

The implementation of this will likely be related to #12649, since some changes will be required to inject a zap.Logger instance into the functions. If we want to track this separately from #12649, I can take this issue.

The functions now support logging so this issue can be worked.
