Drop `core_ext/hash/reverse_merge` require; call HWIA constructor directly

Removes the now-dead `active_support/core_ext/hash/reverse_merge`
require and replaces the two `reverse_merge` usages with explicit
`{ defaults }.merge!(other)` literals.

Also swaps `.with_indifferent_access` call sites for
`ActiveSupport::HashWithIndifferentAccess.new(...)` and adds an
explicit `require 'active_support/hash_with_indifferent_access'` so
the class dependency is documented at the top of `lib/grape.rb`
rather than implicit via the core_ext.
