feat(VInfiniteCarousel): add new component

[J-Sek]

Carousel that loops over

• uses WAAPI instead of plain CSS
• suitable as marquee, for logos and decoration
• supports dragging, arrows, direction, gap, separators, keyboard navigation within, etc.
• immune to scrolling issues (wheel and focus) thanks to overflow: clip

The behavior will be hard to pull in regular carousel - will bloat that simple variant. Better to ship a separate one.

Quick demo:

<template>
  <v-app :theme="light ? 'light' : 'dark'">
    <v-app-bar title="VInfiniteCarousel">
      <v-switch v-model="light" class="mr-4" label="light theme" hide-details />
      <v-switch v-model="pause" class="mr-4" label="pause" hide-details />
      <v-switch v-model="reverse" class="mr-4" label="reverse" hide-details />
      <v-select
        v-model="showArrows"
        :items="[false, true, 'hover']"
        class="mr-4"
        label="show-arrows"
        max-width="140"
        hide-details
      />
      <v-select
        v-model="maskSize"
        :items="[0, 40, 80]"
        class="mr-4"
        label="mask"
        max-width="140"
        hide-details
      />
      <v-select
        v-model="shiftDistance"
        :items="['100%', '50%', 200, '10rem']"
        class="mr-4"
        label="shift-distance"
        max-width="140"
        hide-details
      />
      <v-switch
        :model-value="isRtl"
        class="mr-4"
        label="rtl"
        hide-details
        @update:model-value="rtl[current] = !!$event"
