qmllint: fix unused import warnings

In QTBUG-144377, the ToolTip attached property is inherited from
ToolTip's base as ToolTip is defined via a QML file. Adapt the unused
import warning to recognize attached properties from base types.

Amends 8f60ffc42b732951b2b65fea414d6fcbb68dfde2 that introduced the
warning.

doc: replace directory import from qualified import snippet

The directory import does not seem to make sense here, the documentation
in directoryImports.qdoc states:

Directory Imports rank below any module imports in precedence. If the
same name is defined in a module and in a directory that are both
imported into the same namespace, only the module's type is made
available.

Replace the directory import which can't clash with QtQuick with a
QML module import.

qmllint: parse/lint argument files only once

Before a37e4270a5e66507aeda483ec4d32262096b44cc, qmllint used to create
up to two qqmljsscopes for each file it got as command line parameters.

a37e4270a5e66507aeda483ec4d32262096b44cc enhanced this situation by
avoiding the duplicate scopes, but still processed each file twice (once
by the LinterVisitor for the actual linting and once via lazy-loading
when the file gets pulled in as dependency for another file to be linted).
This lead to QTBUG-146688 where processing the same file into the same
scope has some buggy side-effects and breaks the assumption that
lazy-loaded scopes are never modified after creation.

This patch addresses this issue by making qmllint process each
QML file from its command line once by merging the linting process
and the lazy-loading mechanism together.

Rework QmlJSLinter to work in two stages:
1. collect all files to be linted with prepareFileForBatchLinting()
2. do the actual linting with lintFileInBatch()

 -- Stage 1:
In prepareFileForBatchLinting, set up the file-to-be-linted with a
linting factory to lazy-load it via LinterVisitor instead of
QQmlJSImportVisitor.

"unprepared" files needed by the file-to-be-linted are still loaded
via QQmlJSImportVisitor.

 -- Stage 2:
In lintFile, populate the lazy file if needed and continue with the
rest of the linting process.
At this stage, the QQmlJSScopes of the QML files used by the
current-QML-file-to-be-linted can be populated via lazy construction,
which means that cycle references can be resolved. A first attempt
where all the linting pipeline ran during lazy-loading in stage 1 was
unsuccessful at resolving cyclic dependencies between files.

Remove m_logger from QQmlJSLinter: there may be multiple active loggers,
for example when lazy-loading a file via LinterVisitor during the
linting process of another file.

To avoid QTBUG-146688, make prepareForBatchLinting() return false when
linting would re-populate an already populated scope.
Re-populating a scope breaks all the references to its children which
leads to QTBUG-146688.

Adapt qmllint/main.cpp to prepare all file passed by commandline before
starting to lint them.

Adapt tst_qmllint to:
* simulate clean snippet scope that are actually reused. Snippets
  are not used by other QML code so their scope and children can
  safely be deleted.
* clear the cache when scope re-populating happens on non-snippets. Note
  that clearing the cache for each linted file would be cleaner but
  increases the test runtime by a factor of 2.5x.

qmlpreview: Guard against bindings changing type

Those are not trivial. We actually have to rebuild for them. This holds
not only for switching between literal and script bindings, but also for
turning a literal or script binding into a translation binding (or back):
a translation binding is a live QQmlTranslationBinding, so swapping its
kind means installing or dropping a live binding, which is structural.
