This fixes some fallout from D131282. Currently, add_tablegen() will add the tablegen target to LLVM_EXPORTS and associates the install with LLVMExports. For non-standalone builds, this means that you end up with mlir-tblgen and clang-tblgen in LLVMExports.
However, these projects should instead be using MLIR_EXPORTS/MLIRTargets and CLANG_EXPORTS/ClangTargets. To fix this, add an extra EXPORT option and make use of get_target_export_arg() to create the correct export argument.

Prior to this patch, the `add_tablegen()` macro in
llvm/cmake/modules/TableGen.cmake added the install rule only if
`project` matched `LLVM` or `MLIR`. This patch adds an optional
`DESTINATION` argument, which, if non-empty, decides whether (and where)
to install the tablegen tool, thus eliminating the need for
project-specific overrides. This patch also updates all other
invocations of the `add_tablegen()` macro.

`enableSplitting` simply enables/disables whether we should split
or use the full buffer. `insertMarkerInOutput` toggles if split markers
should be inserted in between prcessed output chunks.
These options allow for merging the duplicate code paths we have
when splitting is optional.

This commit enables providing long-form documentation more seamlessly to the LSP
by revamping decl documentation. For ODS imported constructs, we now also import
descriptions and attach them to decls when possible. For PDLL constructs, the LSP will
now try to provide documentation by parsing the comments directly above the decls
location within the source file. This commit also adds a new parser flag
`enableDocumentation` that gates the import and attachment of ODS documentation,
which is unnecessary in the normal build process (i.e. it should only be used/consumed
by tools).

https://reviews.llvm.org/D124075 causes MLIR to no longer build
when using make rather than ninja, due to a tablegen-generated
header being used before it is created.
It seems that this is related to the use of LLVM_ENABLE_OBJLIB when
using add_tablgen with a non-Ninja/Xcode generator. In that case an
intermediate objlib target is generated.
This patch fixes the issue by a) declaring dependencies in
add_tablegen for mlir-pdll and b) making sure those dependencies
are added to the objlib target.

This essentially sets up mlir-pdll to function in a similar manner to mlir-tblgen. Aside
from the boilerplate of configuring CMake and setting up a basic initial test, two new
options are added to mlir-pdll to mirror options provided by tblgen:
* -d
This option generates a dependency file (i.e. a set of build time dependencies) while
processing the input file.
* --write-if-changed
This option only writes to the output file if the data would have changed, which for
the build system prevents unnecesarry rebuilds if the file was touched but not actually
changed.

This commit adds support for processing tablegen include files, and importing
various information from ODS. This includes operations, attribute+type constraints,
attribute/operation/type interfaces, etc. This will allow for much more robust tooling,
and also allows for referencing ODS constructs directly within PDLL (imported interfaces
can be used as constraints, operation result names can be used for member access, etc).

This commits adds a C++ generator to PDLL that generates wrapper PDL patterns
directly usable in C++ code, and also generates the definitions of native constraints/rewrites
that have code bodies specified in PDLL. This generator is effectively the PDLL equivalent of
the current DRR generator, and will allow easy replacement of DRR patterns with PDLL patterns.
A followup will start to utilize this for end-to-end integration testing and show case how to
use this as a drop-in replacement for DRR tablegen usage.

This commits starts to plumb PDLL down into MLIR and adds an initial
PDL generator. After this commit, we will have conceptually support
end-to-end execution of PDLL. Followups will add CPP generation to
match the current DRR setup, and begin to add various end-to-end
tests to test PDLL execution.

This is a new pattern rewrite frontend designed from the ground
up to support MLIR constructs, and to target PDL. This frontend
language was proposed in https://llvm.discourse.group/t/rfc-pdll-a-new-declarative-rewrite-frontend-for-mlir/4798
This commit starts sketching out the base structure of the
frontend, and is intended to be a minimal starting point for
building up the language. It essentially contains support for
defining a pattern, variables, and erasing an operation. The
features mentioned in the proposal RFC (including IDE support)
will be added incrementally in followup commits.
I intend to upstream the documentation for the language in a
followup when a bit more of the pieces have been landed.
