Ensure that Typed Properties are spaced correctly

[carusogabriel]

This new rule checks for things like:

• one space between the typehint and the property name
• one space between the typehint and the property's modifiers
• no space between the nullability symbol and the typehint

This rule does not check for:

• How many lines the typed properties are separated by
• If two consecutive properties have default values, the = sign will be aligned

This also falls under the PSR-12, by the item 4.3:

There MUST be a space between type declaration and property name.

The comment for this rule and the others are on lines 360-362:

coding-standard/lib/Doctrine/ruleset.xml

Lines 360 to 362 in d025e82

	<!-- Require types to be written as natively if possible;
	require iterable types to specify phpDoc with their content;
	forbid useless/duplicated information in phpDoc -->

@carusogabriel The description looks wrong:

no space between the typehint and the property name
no space between the typehint and the property's modifiers

I think there should be one space
