UI: Adjust and fix shader node descriptions

The tooltips added for shader nodes in D15309 are very helpful already.
This commit makes a few tweaks to make them more consistent, concise,
and includes some fixes. Note that this might move some descriptions
further away from the wording in the manual.

* Make wording more concise
  * Start fewer new sentences
  * Use "For Example" slightly less
  * Avoid repeating the node's name unnecessarily
* Spelling/grammar fixes
  * Don't capitalize some words
  * Use consistent verb conjugation
  * Use ASCII characters/more common quote symbols
* Corrections to information
  * Plural/singular corrections
  * "smoke domains" -> "volume grids"
  * Fix tooltip for separate and combine color nodes
  * Refer to color sockets as colors rather than "images"
* Avoid "advice" in a few places, which should be left for the manual
* Remove information for sockets and could be in their tooltips
* Avoid referring to the locations of a property in the UI
* Avoid manual newlines (mostly reserve for "Note:")
  * Leave UI code in control of wrapping, which is more consistent
* Add some information
  * That the UV map and color attribute nodes use a default
  * That Voronoi is "based on the distance to random points"
  * Add "(Deprecated)" to old color combine and separate nodes
