We have migrated the main docs to the ASF site,

Points the docs to the ASF version.

* [CI] Improve the docs generation script

* [RELAY] Add MergeCompilerRegions pass

This pass is part of the flow to support creating compiler
regions with multiple outputs. It should be called after
AnnotateTarget and will merge together regions that share
the same target to create larger compiler regions that can
be off-loaded to external codegens.

This pass implements an algorithm to ensure that during the
merging, no data dependency issues are created. See the tests
for an example of this case.

* [RELAY] Annotate compiler_ends on each edge

This alters the behaviour of the AnnotateTarget
pass to enforce the property that all compiler
annotations exist along a single data flow edge.
Specifically, this means they should have exactly
one parent and one child.

* [NODE][IR] Introduce StructuralHash for the Unified IR.

This PR introduces a new way to handle structural hash for the unified IR.

- Each object can now register an optional SEqualHash function, which
  describes how to reduce its structural equality to sequence of hash values.
- Optionally, the object can choose to allow labeling of vars(e.g. function parameters)
  by calling DefHash
- We implemented a non-recursive structural hasher that maintains its own stack
  to traverse te IR.

This PR also improves the hash value property from the previous relay's hash utility.
In particular, the graph node mode hashs a DAG differently from a tree
by attaching an unique occurence index to each graph node.

In all of the test cases so far, structural_hash is consistent with structural_equal.
- if structrual(x, y) then structural_hash(x) == structural_hash(y)
- if structural_hash(x) == structural_hash(y) then highly likely structural_equal(x, y)
  - hash no collison is found in our testcases.

Ideally we should work on automatically generating these functions in the future.

* Fix cases for EnvFunc and Array dims

* [NODE][IR] Introduce StructuralEqual Infra for the Unified IR.

This PR introduces a new way to handle structural equality
for both TIR and relay nodes in an extensive way.

- Each object can now register an optional SEqualReduce function, which
  describes how to reduce its structural equality to another instance
  into equality of the children.
- Optionally, the object can choose to allow remapping of vars(e.g. function parameters)
  by calling DefEqual
- We implemented a non-recursive structural equality checker that
  recursively traverses the objects and does the structural equality checking.

This PR also fixes a few potential problems in previous relay's AlphaEqual.

- In particular, the new structural equality relation will be communicative.
- It is can be dangerous to use same_as relation to quickly check equality,
  demonstrated by the following case. (%x, %y) are shared vars between two functions.

- function0: fn (%x, %y) { %x + %y }
- function1: fn (%y, %x) { %x + %y }

The new structural equal is intented to supersede AlphaEqual and AttrsEqual.

Follow-up PRs should be performed to redirect the existing usages, and removes
the corresponding implementation.

'fannotate' in the annotate_target pass was designated as
static. This meant that if you use the pass to annotate
more than one codegen, its value is not updated when the
target changes resulting in incorrect annotation.

* [RELAY] Added an AnnotatedRegionSet utility class

In many of the passes involved in graph partitioning,
we need to extract and manipulate annotated regions.
This class simplifies the extraction of regions from a relay
expression containing region begin and end annotations
as well as providing utility functions to query these
regions and merge them.
