Fix typos, punctuation, etc. in XML doc comments

* Simple stuff: typos and missing punctuation and line breaks.

 * Sometimes, two method overloads have quite different documentation.
   Rephrase these to make them more similar.

 * Minor rephrasings like in a previous commit (e.g. "...how output
   should be formatted", "initializes a new instance of...").

 * Obvious incorrect type references in comments. These appear mostly
   in `Utilities/LinqBridge.cs` (nullable vs non-nullable).

 * Remove factually incorrect statement about exceptions thrown.

 * Remove comments for explicitly implemented interface methods.
