[Flang][OpenMP] Allow copyprivate and nowait on the directive clauses (#127769)

Issue:
- Single construct used to throw a semantic error for copyprivate and
  nowait clause when used in the single directive.
- Also, the copyprivate with nowait restriction has been removed from
  OpenMP 6.0

Fix:
- Allow copyprivate and nowait on both single and end single directive
- Allow at most one nowait clause
- Throw a warning when the same list item is used in the copyprivate clause
  on the end single directive

From Reference guide (OpenMP 5.2, 2.10.2):
```
!$omp single [clause[ [,]clause] ... ]
loosely-structured-block
!$omp end single [end-clause[ [,]end-clause] ...]

clause:
  copyprivate (list)
  nowait
  [...]

end-clause:
  copyprivate (list)
  nowait
```

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.
