  [mlir][LLVM][ROCDL] Add buffer oob mode module flags, flag interfaces (#202729)

Now that the out-of-bounds mode for buffer accesses will be controlled
by a module flag and is no longer a function of the subtarget triple (as
of #160922) and since `ptr addrpace(7)` lowering will start respecting
this mode soon, add MLIR-level support for setting this flag.

After a few iterations, I think adding this module flag to
`llvm.module.flags` but adding interfaces for module flag attributes (so
that those wishing to set this flag don't need to know it has `max`
combining semantics or look up the enum values) is a
minimally-disruptive way to get a more ergonomic wrapper around this
functionality.

AI note: AI generated the code hehe, I reviewed it. The documentation
update to ModuleFlagsOp is mine.

(The LLVM PR that would want people to start explicitly setting
`relaxed` is #134329)
