[IPEX] Fix embedding and ControlNet

Re-add setting lost as part of e294e46d

Fix styles

Allow pasting in WIDTHxHEIGHT strings into the width/height fields

Fix wrong implementation in network_oft

Cast `torch.bmm` args into same `dtype`.

Fixes the following error when using Text Inversion embedding (#14224):

primitive
```

remove clean_text()

Update launch_utils.py - fixes repetead package reinstalls

Fixes failing dependency checks for extensions having a different package name and import name (for example ffmpeg-python / ffmpeg), which currently is causing the unneeded reinstall of packages at runtime.

In fact with current code, the same string is used when installing a package and when checking for its presence, as you can see in the following example:

> launch_utils.run_pip("install ffmpeg-python", "required package")
[ Installing required package: "ffmpeg-python" ... ]
[ Installed ]

> launch_utils.is_installed("ffmpeg-python")
False

... which would actually return true with:

> launch_utils.is_installed("ffmpeg")
True

Add import_hook hack to work around basicsr/torchvision incompatibility

slight optimization for mask and mask_composite 

Fixes #13985

Fix `save_samples` being checked early when saving masked composite

Re-add `keyedit_delimiters_whitespace` setting lost as part of commit e294e46d
