 * @description creates BEM modifiers based on transferred prefix (base BEM class) & modifiers list.
 * camelCase modifiers names will be transformed to the kebab-case.
 * @param prefix string that classes start with (base BEM class).
 * @param modifiers list of options that will serve as state BEM modifiers.
 * @returns computed classes starting with "prefix" and ending with form state BEM modifier.
 * @example
 *  const result = useBem('va-component', computed(() => pick(props, ['success, noError'])))
 *  // if success & noError are `true`
 *  { ...result }: { 'va-component--success': true, va-component--no-error: true }
 *  result.asObject.value: { 'va-component--success': true, va-component--no-error: true }
 *  result.asArray.value: ['va-component--success', 'va-component--no-error']
 *  result.asString.value: 'va-component--success va-component--no-error'
