[cmake] Add minor version to library SONAME (#79376)

We need to do this now that we are bumping the minor release number when
we create the release branch.

This also results in a slight change to the library names for LLVM. The
main library now has a more convential library name:
'libLLVM.so.$major.$minor'. The old library name: libLLVM-$major.so is
now a symlink that points to the new library. However, the symlink is
not present in the build directory. It is only present in the install
directory.

The library name was changed because it helped to keep the CMake changes
more simple.

Fixes #76273

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.
