[MLIR][Target/Cpp] Fix variable naming conflict for function declarations (#147927)

This is a fix for https://github.com/llvm/llvm-project/pull/136102. It
missed scoping for `DeclareFuncOps`.
In scenarios with multiple function declarations, the `valueMapper`
wasn't updated and later uses of values in other functions still used
the assigned names in prior functions.

This is visible in the reproducer here
https://github.com/iree-org/iree/issues/21303: Although the counter for
variable enumeration was reset, as it is visible for the local vars, the
function arguments were mapped to old names. Due to this mapping, the
counter was never increased, and the local variables conflicted with the
arguments.

This fix adds proper scoping for declarations and a test-case to cover
the scenario with multiple `DeclareFuncOps`.

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
