Doc: Adding mark-up to boolean default values.

Default values should have mark-up to denote that they are code.
This commit changes:
-"property is true" to "property is \c true".
-"Returns true" to "Returns \c true".
-"property is false" to "property is \c false".
-"returns true" to "returns \c true".
-"returns false" to "returns \c false".

src/3rdparty and non-documentation instances were ignored.

Task-number: QTBUG-33360
