I updated the two functions fetchIndex and fetchIndexesViaSqlDB to use currentIndex.Visible = !isIndexInvisible(visible)

This pull request introduces a new feature targeting MySQL version 8 and above, where the concept of invisible indexes has been introduced. Specifically, this PR adds a Visible field to the schema.Index struct, allowing users to easily filter out invisible indexes.
We encountered an issue with ghostferry where an invisible index was mistakenly selected as the shardingKeyIndexName. To address this, we initially applied a patch directly to the ghostferry project, as documented in ghostferry PR #383. This current PR seeks to integrate those changes into the upstream codebase for broader applicability. Part of Shopify/ghostferry#384.
