Add the properties "implicitTextPadding" and "textPadding"
to MenuItem. They can be used by the style to ensure that
all MenuItems inside the same Menu end up left-aligned
WRT text.

Each MenuItem should set implicitTextPadding to be the
needed space from the left edge of the contentItem to
the text label. QQuickMenu will then iterate over all
the MenuItems inside the same Menu, and set textPadding
to be the maximum implicitTextPadding found.

All MenuItems should then use textPadding (which will end
up the same for all MenuItems) to position the text.

This API is meant to solve the problem that MenuItems
inside a single Menu can have different contents. Some
can be checkable, some can have an icon, some are just
plain text. And for several of our styles (e.g macOS and
Windows), we want the text to be left-aligned regardless
of that. Without this API, The checkmark inside a
checkable MenuItem would be left-aligned with the text
inside a plain MenuItem etc.

[ChangeLog][Controls][MenuItem] A MenuItem now has two
new properties (implicitTextPadding and textPadding)
that can be used for aligning the text across all
MenuItems inside a Menu.

Several of the styles offers a Menu with a drop shadow. And the shadow
is drawn on the outside of the Menu. This works fine when the menu
is shown as an item in the scene, since Quick allows controls to
draw out-of-bounds. But when we now place the Menus inside native
windows, this will no longer be the case, as the windows will be
resized to fit the Menus, shadows excluded.

To solve this, this patch will make the Menus bigger, without
touching the size of the background, so that they include the
drop shadows. This is easily done by pushing the background items
a bit in, using insets.

The next issue is that when the application, or the MenuBar,
requests a Menu to open at at specific position, we want the
top left corner of the menu frame to be placed at this position.
But since the Menu background is now shifted into the Menu, we
need to teach QQuickPopup and and QQuickMenu to take insets into
account when positioning a popup/menu. Taking the insets into
account like this should be fine, since they're documented to be
used for this exact purpose, of adding drop shadow effects.

Add support in quick table view to reorder rows and columns.

The properties 'movableColumns' and 'movableRows' enable the header
view to reorder columns and rows, which are disabled by default.
These properties allow the user to drag and drop sections for the
row and column reordering. It is to be noted that these properties
apply only to the header view (HorizontalHeaderView and
VerticalHeaderView) and do not apply to the TableView directly.
The change in the header view will be synced to the table view by
setting the corresponding view to the syncView property in the
header view.

The TableView can also explicitly reorder columns and rows through
the public API moveColumn() and moveRow().

This ensures that the user won't inadvertently base the customizations
on top of the native styles, but also saves adding the extra code that
using QtQuick.Templates would require. The first sentence of the

The macOS style is currently falling back to use
a CheckIndicator from the Fusion style. This doesn't look
very native on macOS.

This patch will therefore implement the missing
CheckIndicator for the macOS style, and try to make
it look as native as possible.
