* [RUNTIME] Introduce RValue reference(move) support to TypedPackedFunc

This PR introduces RValue reference support the PackedFunc calling convention to address the above issue.
Specifically, when an argument is a r-value reference, we will use a assign a different type code(`kObjectRValueRefArg`),
and pass `Object**`  (the address to the Object pointer) instead through the values array.
The callee can choose to move out this Object pointer and set the original Object pointer from the caller side to be nullptr.

We also add an experimental move support to the python side(marked as _move so to indicate the dev nature).
This enhancement will enable copy on write optimizations through out the TVM stack.

This PR refactors the serialization mechanism to support general
serialization of leaf objects into bytes.

The new feature superceded the original GetGlobalKey feature for singletons.
Added serialization support for runtime::String.

In newer versions of LLVM, this header is no longer included by one of
the already included headers in llvm_common.h, so include it explicitly.

* [RELAY] Add 'check' functions to MergeComposite

Currently, MergeComposite can only perform structural
matches. This patch introduces the ability to specify
a 'check' function alongside the pattern which can include
custom logic to determine whether an extracted pattern
should be merged.

For example, if you only want to merge 'NHWC' convolutions,
you can specify a 'check' function which queries the
data_layout value of the extracted pattern (see the test).

* [RELAY][BYOC] Support composite functions in AnnotateTarget

This patch introduces support to annotate composite functions
in the AnnotateTarget pass. In order for a composite function
to be annotated, you should name it according to the style:

{codegen}.{name}
eg. dnnl.add_relu

This intrinsic was removed in LLVM 11.

LLVM 11 added support for scalable vectors, and now the number of
elements in a vector is represented by a llvm::ElementCount class,
not just a number.

LLVM 11 is introducing a separate class to represent alignment.
The functions in IRBuilder that create aligned loads and stores,
and which accept the alignment as an unsigned value have been
deprecated (and now cause warnings to be emitted).
