Subject: [PATCH] Blocks: Include the offending block name in registration
 error notices.

Three of the four `_doing_it_wrong()` calls in `WP_Block_Type_Registry::register()` emitted a generic message that did not identify which block name triggered it, making it hard to locate the offending registration. The notices for non-string names, uppercase characters, and a missing namespace prefix now include the received value (the type via `gettype()` for non-strings, and the escaped name otherwise), matching the existing "already registered" notice that did already report the name.

Developed in https://github.com/WordPress/wordpress-develop/pull/11478.
Follow-up to r44108.

Props manishxdp, desrosj, benjgrolleau, westonruter.
Fixes #65039.
