[OpenMP] Introduce omp.target_allocmem and omp.target_freemem omp dialect ops. (#145464)

This PR introduces two new ops in omp dialect, omp.target_allocmem and
omp.target_freemem.
omp.target_allocmem: Allocates heap memory on device. Will be lowered to
omp_target_alloc call in llvm.
omp.target_freemem: Deallocates heap memory on device. Will be lowered
to omp+target_free call in llvm.


Example:
  %1 = omp.target_allocmem %device : i32, i64
  omp.target_freemem %device, %1 : i32, i64

The work in this PR is C-P/inspired from @ivanradanov commit from
coexecute implementation:
[Add fir omp target alloc and free
ops](https://github.com/ivanradanov/llvm-project/commit/be860ac8baf24b8405e6f396c75d7f0d26375de5)
[Lower omp_target_{alloc,free} to
llvm](https://github.com/ivanradanov/llvm-project/commit/6e2d584dc93ff99bb89adc28c7afbc2b21c46d39)

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM

Consult the Getting Started with LLVM page for information on building and running LLVM.

For information on how to contribute to the LLVM project, please take a look at the Contributing to LLVM guide.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
