[analyzer] Consolidate the va_list checkers (#156682)

Previously the analyzer had an undocumented top-level checker group
called `valist` which offered several checkers to detect use of
uninitialized `va_list` objects and leaks of `va_list`s.

As the responsibilities of these checkers were messily intertwined and
`va_list` is a rarely used language feature, this commit simplifies the
situation by consolidating these checkers into a single checker which
will be called `security.VAList`.

Note that I'm choosing the capitalization `VAList` to be consistent with
the example of the AST node type `VAArgExpr`. I updated many variable
names to ensure that `ValistChecker.cpp` uses this spelling everywhere
(in CamelCased names). I'm planning to rename `ValistChecker.cpp` to
`VAListChecker.cpp` in a follow-up commit.

This commit also adds documentation for this checker in checkers.rst.

Among the test files I preserved the existing separation but I
eliminated some duplicated cases now that there is no way to separately
enable the old sub-checkers.

For the background of this change see also the discourse thread

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
