Fix fieldMetadata sync validation exceptions caught in exception handler (#10789)

## Context
Field metadata service was reusing validators from
validate-**OBJECT**-metadata-input which were throwing ObjectMetadata
exceptions not handled in fieldMetadataGraphqlApiExceptionHandler and
were going to Sentry.
To solve the issue since this validator is associated with both fields
and objects I'm moving the util to the root utils folder of metadata
module and throwing a common metadata user input exception
