Server should validate that deephaven:type and arrow type match

[niloc132]

Historically, Deephaven would accept arrow int8 columns for boolean values, to be able to track true/false/null. That has changed on the server, and for a time the server did not validate that a client would correctly send individual bits instead of bytes for each value. This has been changed by #3401.

However, the other custom deephaven:type mappings should also be validated, to ensure they are being sent as the expected arrow type.
