treewide: standardize shell integration options

Standardize all 'programs.<PROGRAM>.enable<SHELL>Integration' options
with the following new functions:

- lib.hm.shell.mkBashIntegrationOption
- lib.hm.shell.mkFishIntegrationOption
- lib.hm.shell.mkIonIntegrationOption
- lib.hm.shell.mkNushellIntegrationOption
- lib.hm.shell.mkZshIntegrationOption

These functions should default to their corresponding global option:

- shell.enableBashIntegration
- shell.enableFishIntegration
- shell.enableIonIntegration
- shell.enableNushellIntegration
- shell.enableZshIntegration

All these global options default to the 'shell.enableShellIntegration'
value.

This hierarchy standardizes the shell integration and increases end-user
flexibility.

BREAKING CHANGE: This modifies the following inconsistent default values
from 'false' to 'true':

- programs.zellij.enableBashIntegration
- programs.zellij.enableFishIntegration
- programs.zellij.enableZshIntegration
