Merge bitcoin-core/gui#313: qt: Optimize string concatenation by default
a02c970eb001b456d74ddc30750fe8b55348ddac qt, refactor: Revert explicit including QStringBuilder (Hennadii Stepanov)
3fd3a0fc87a81d42755246830124833e9ca3f0a9 qt, build: Optimize string concatenation (Hennadii Stepanov)

Pull request description:

  From [Qt docs](https://doc.qt.io/qt-5/qstring.html#more-efficient-string-construction):
  > ... multiple uses of the \[`QString`\] '+' operator usually means multiple memory allocations. When concatenating n substrings, where n > 2, there can be as many as n - 1 calls to the memory allocator.

  With this PR
  > ... the '+' will automatically be performed as the `QStringBuilder` '%' everywhere.

  The change in the `src/Makefile.qt.include` file does not justify submitting this PR into the main repo, IMHO.
