opt: Add VulkanMemoryModelDeviceScope to trim (#5544) 
Add the VulkanMemoryModelDeviceScope capability to the capability
trimming pass. According the the spec, "If the Vulkan memory model is
declared and any instruction uses Device scope, the
VulkanMemoryModelDeviceScope capability must be declared." Since this
case, based on the type of an operand, is not covered by the JSON
grammar, it is added explicitly.

// Those are expected changes caused by the test process:
// - SPV is assembled. -> capability goes from text to number.
// - SPV is optimized.
// - SPV is disassembled -> capability goes from number to text.
// - CHECK rule compares both text versions.
// Because some capabilities share the same number (aliases), the text
// compared with the CHECK rules depends on which alias is the first on the
// SPIRV-Headers enum. This could change, and we want to easily distinguish
// real failure from alias order change. This test is only here to list known
// alias transformations. If this test breaks, it's not a bug in the
// optimization pass, but just the SPIRV-Headers enum order that has changed.
// If that happens, tests needs to be updated to the correct alias is used in
// the CHECK rule.
