[Bug]: Error when using --precision full

[huchenlei]

Checklist

• The issue exists after disabling all extensions
• The issue exists on a clean installation of webui
• The issue is caused by an extension, but I believe it is caused by a bug in the webui
• The issue exists in the current version of the webui
• The issue has not been reported before recently
• The issue has been reported before but has not been fixed yet

What happened?

A1111 report error on generation.

Steps to reproduce the problem

• Add --precision full to command line arg
• Load a half precision checkpoint
• Click generate
• Observe error message

What should have happened?

Generation without error.

### Additional information

_No response_

[huchenlei]

--precision full used alone will produce the error, but when used together with --no-half, it seems fine.

At least we should notify people these 2 args should be used together, or just make --no-half an alias of --precision full
