Refactored attribute limits to be controlled by the LoggerProvider

[evanlauer1]

Big Context

Logging Support is being added to hs-opentelemetry. Logging spec

Small (This PR) Context

LoggerProviders should control the AttributeLimits for Loggers. Previously, the entirety of LogAttributes was provided to the emitLogRecord function instead of passing the attributes via a HashMap Text AnyValue and AttributeLimits via a LoggerProvider accessed through the provided Logger. Relatedly, LogAttributes should be able to be changed after the creation of the Logger, but that will be added later.

Is there anything about this that addresses the part of the spec that says this:

There SHOULD be a message printed in the SDK’s log to indicate to the user that an attribute was discarded due to such a limit. To prevent excessive logging, the message MUST be printed at most once per LogRecord (i.e., not per discarded attribute).

This is actually something that we don't support on the tracing side (which says effectively the same thing). I wanted to support it on the tracing side using OTel logging, so it's a bit of an ouroboros 😆

I think enough of the logging interface is in place that we should be be able to support this use case now though.

This is addressed by the next downstream pull request in the stack. The change was to large to be reasonably contained in this PR.
