Add validation to instrument and view name

[joaopgrassi]

Changes

This PR adds validation to the instrument names as described in the Instrument spec.

Summary of changes:

• Instruments with invalid names are ignored and an event is logged
• Views added with a name also are validated in the same way with some particularities:
  • Overloads of AddView that accepts the name or MetricStreamConfiguration fail-fast if the name provided is invalid
  • Overloads where the Func is specified cannot be validated right away. They are only validated on instrument publish, and if invalid, are ignored with a log.
• Added new events in OpenTelemetrySdkEventSource to log the above cases
• Tests

Closes #2424

For significant contributions please make sure you have completed the following items:

• CHANGELOG.md updated for non-trivial changes
