SI-9620: add doc annotation to hide specific conversions

This commit will introduce the doc annotation `@hideImplicitConversion`.
By specifying which conversions to hide, the user can "toggle" which
conversions are kept in the parsed entity.

This implementation is a better workaround than hardcoding which ones to
ignore when running scaladoc.
