[shell] Clean OTA commands & remove base64 commands (#32396)

* [shell] Clean OTA commands

1. Remove obsolete "apply" and "notify" commands. These
   actions are invoked automatically by OTA requestor.
2. Do not post tasks onto CHIP thread - shell commands
   are already run on CHIP thread.
3. Do not print error codes. They are already printed
   by shell core.

* [shell] Remove base64 commands

Base64 encoding/decoding is not specific to Matter so base64
shell commands are not useful on actual Matter devices.
