Enforces valid v-if usage for Vue templates.

This rule reports v-if directives in following cases:

The directive has an argument. E.g. <div v-if:aaa="foo"></div>
The directive has a modifier. E.g. <div v-if.bbb="foo"></div>
The directive does not have an attribute value. E.g. <div v-if></div>
The same element also has v-else or v-else-if. E.g. <div v-if="foo" v-else></div>
