Search for resource files in .qt/rcc instead of only looking in
the .rcc folder, and update the resource file mapper in
setLoadPaths to actually use the resource files.

Amends d0fcb75aab1b5a91260fb378d761257e1f2e4787 to:
 a) work on more sophisticated project structures with
    "prefer"-directives
 b) use resource files for all qmlls modules (previously only the
    linting module was using resource files)

Also move the methods to find .qrc files into qqmljsutils_p.h and add a
new test file.

This patch fixes the spurious warning about SettingsData being not found
and the missing completion suggestion for the SettingsData type in
qml/popups/AdminDialog.qml on Ekke's project attached at QTBUG-126504.
The build folder structure was mimicked in sophisticatedBuildFolder for
the test.

Also change DomEnvironment::semanticAnalysis() to return a value instead
of a reference, and rename SemanticAnalysis::setLoadPaths to
SemanticAnalysis::updateLoadPaths because it will set the loadpaths on
all copies of semanticAnalysis instead of just setting it on the current
one.

Move the methods used to set the linting category level from

If we manually define the logging category function, we should really
avoid the macro for declaring it. When exporting a logging category, we
need to use the special export macro since we shouldn't rely on the
internals of the declaration macro for placing the export. The same
holds for static logging categories.

Furthermore, consistently call the functions for lcQml and lcJs.

We also need to fix the namespaces in qmlls now since the logging
categories are decidedly not in either of the used namespaces, and the
namespaces are all inside any Qt namespace.

Add a -I option that specifies additional import paths used to find QML
modules.
Add a -E option that searches QML modules in the import paths specified
by the environment variables QML_IMPORT_PATH.

Add an import path field to QQmlCodeModel with setters and getters
that may now consist of more than just
`QLibraryInfo::path(QLibraryInfo::QmlImportsPath)`.

Extract some common code used to read, check and inform about directories
used from environment variables or command line options into static
methods. This would allow other tooling, like qmllint, to print the same
warnings when using environment variables, for example.

Add a new test tst_qmlls_cli that allows to test qmlls behavior
when fed with different combinations of -I, -E and -b (for build
directories) options. The test also enables checking that warnings are
correctly emitted and that import paths are correctly used during
linting via qmlls.

Note that the warnings emitted by qmlls when using -b were
enhanced, partially due to the refactoring of the static helpers to read
directory names from environment and command line options. Also note
that qmlls was informing twice about possibly using .qmlls.ini files
before this commit, so also remove the redundant warning.

When iterating, pass it by const ref. When "adding" pass it by rvalue
ref. In the few places where that clashes, copy it explicitly.
