Create Translation Bindings without CompiledData::Binding

To add translation bindings to qmltc, the methods used to create
translation bindings need to be adapted to work without
QV4::CompiledData::Binding as it is not available from qmltc. Instead,
information already available from the QQmlJSScope should be used, along
with a newly introduced helper class QQmlTranslation.

Details:
Add a QQmlTranslation class that represents a call to qsTr, qsTrId etc
that knows how to translate itself (without needing any
ExecutableCompilationUnit or Binding). It encapsulates the
information needed to create a translation binding.

ExecutableCompilationUnit::bindingValueAsString refactored
so its functionality can be used without Binding.
Instead, it uses only the translationId, see
ExecutableCompilationUnit::translateFromId
and
ExecutableCompilationUnit::translateFrom.

Refactored QQmlTranslationBinding to work with QQmlTranslation instead
of CompiledData::Binding.
Same for QQmlCppBinding::createTranslationBindingForBindable,
QQmlTranslationPropertyBinding::create and
QQmlCppBinding::createTranslationBindingForNonBindable.

Changed TranslationBindingInformation to work without
CompiledData::Binding, and also removed static unused
QString ProxyTranslator::originStringFromInformation(
   const TranslationBindingInformation &translationBindingInformation)
as I could not find out what this origin string is.

Same for the translation debugging in qmldb_preview.

Added QmltcCodeGenerator::generate_createTranslationBindingOnProperty.

Added #if to avoid compilation error for standalone DOM compilation due
to the new QQmlTranslation class.
