[Bug]: Don't convert -webkit-line-clamp: initial to -webkit-line-clamp: none

[nex3]

Describe the bug

Currently, postcss-reduce-initial will convert -webkit-line-clamp: initial to -webkit-line-clamp: none. However, the latter has dramatically lower browser compatibility (only Firefox supports the value none, not Edge or Safari).

Expected behaviour

-webkit-line-clamp: initial should be left as-is until -webkit-line-clamp: none is widely supported, or unless Firefox is the only targeted browser in the browserslist.

Steps to reproduce

1. Go to https://cssnano.co/playground/
2. Paste in a {-webkit-line-clamp: initial}
