[flang][OpenMP] share global variable initialization code (#138672)

Fixes #108136

In #108136 (the new testcase), flang was missing the length parameter
required for the variable length string when boxing the global variable.
The code that is initializing global variables for OpenMP did not
support types with length parameters.

Instead of duplicating this initialization logic in OpenMP, I decided to
use the exact same initialization as is used in the base language
because this will already be well tested and will be updated for any new
types. The difference for OpenMP is that the global variables will be
zero initialized instead of left undefined.

Previously `Fortran::lower::createGlobalInitialization` was used to
share a smaller amount of the logic with the base language lowering. I
think this bug has demonstrated that helper was too low level to be
helpful, and it was only used in OpenMP so I have made it static inside
of ConvertVariable.cpp.

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.
