Automatic qmlls support (experimental)

Browse Source 
Looks for qmlls (the qml language server of Qt) and if available
and set in the preferences uses it instead of the embedded code
model for the supported features.

Its usage is driven by two flags that can be set in the QtQuick > QML/JS
Editing preferences: "use qmlls" activates the use of qmlls if available;
"use latest qmlls" always uses the qmlls of the latest Qt, instead of
the one of the target (with the one used to compile QtCreator as
fallback).

To support disabling/enabling of qmlls as soon as one changes the
preferences the singleton QmllsSettingsManager can emit a signal
on changes.
It also keeps track of the latest qmlls binary known.

QmlJS::ModelmanagerInterface::ProjectInfo is also extended to keep track
of the qmlls binary.

QmlJSEditorDocument uses the ProjectInfo and QmllsSettingsManager to
decide if a LanguageClient::Client should be started for that
document.

The client uses the QmllsClient subclass to keep track of the path of
the qmlls clients and use the same qmlls process or all files that
use the same binary.

Currently qmlls <6.4.0 are not considered because they might have too
many issues.

The enabling/disabling of warnings and highlight is a bit cumbersome
because they are handled together in the semantic highlighter, but
must be handled separately depending on the qmlls capabilities.

The disabling is done at the latest moment stopping the visualization
of the embedded model warnings/highlights/suggestions.
The computation of the semantic info is not suppressed to support the
other features (find usages, semantic highlighting if active,...).
When qmlls supports more features a complete removal of the semantic
info construction could be evaluated.
