dpu: llvm & clang: remove builtin dpu_seqread_get

The builtin lowering is ill-formed with arithmetic+comp+branch instruction.
Emit a splitted version in EmitInstrWithCustomInserter to recombine later
is too complicated.

This commit revert to what it was before, a simple function call in the runtime library.

This revert the followings:

"dpu: llvm: seqread_get: force incr to be a positive signed char to be optimized"
This reverts commit cfc4828

"dpu: llvm: enumerate every nc condition to convert pageSizeLog2"
This reverts commit 3c67e43.

"dpu: llvm & clang: add builtin dpu_seqread_get"
This reverts commit 301a2e2

Add possible deprecation warning to dpu clang (upmem#73)

The variable OS_DEPRECATION_WARNING is defined in the dpu_tools CMakeLists.txt, and adds a deprecation on affected distributions.

set cmake policies for CMP0114 and CMP0116 to OLD to avoid warning

* Harmonize cmake_policy() across standalone builds of all projects

Move `cmake_policy()` settings from `llvm/CMakeLists.txt` into a shared
`cmake/modules/CMakePolicy.cmake`.  Include it from all relevant
projects that support standalone builds, in order to ensure that
the policies are consistently set whether they are built in-tree
or stand-alone.

Differential Revision: https://reviews.llvm.org/D136572

* Disable windows and macos github actions since we don't support those systems.
