ispyisail 9e070f9bce Log project load times, split by phase
Requested in #553 to compare Qt5 and Qt6 builds. QET already reports how
long the elements collection takes to load (ElementsCollectionWidget::
reload); this adds the equivalent for opening a project.

The phases are reported separately rather than as a single total. Reading
the XML and building the objects is mostly independent of the Qt version,
whereas refreshing the diagrams is graphics-scene work -- a single number
would mix the two and could suggest a Qt version makes no difference when
the part that changed is simply not where the time goes. Measured on the
example projects, XML parsing is 3-7% of the total and diagram
construction 77-83%, so the distinction matters in practice.

QETProject::openFile() reports the total with the parse/build split, and
readProjectXml() reports the build phases:

  Project content built in 1.391 seconds (elements collection 0.009,
    diagrams 1.153, terminal strips 0, refresh 0.196, database 0.033)
  Project "example.qet" (3399 KiB) opened in 1.505 seconds
    (xml parsing 0.11, content 1.395)

Logged with qInfo(), matching the existing collection timer, so it lands
in the normal log without a debug build.
