[MLIR][LLVMIR] Import calls with mismatching signature as indirect call (#135895)

LLVM IR currently [accepts](https://godbolt.org/z/nqnEsW1ja):
```
define void @incompatible_call_and_callee_types() {
  call void @callee(i64 0)
  ret void
}

define void @callee({ptr, i64}, i32) {
  ret void
}
```

This currently fails to import. Even though these constructs are
dangerous and probably indicate some ODR violation (or optimization
bug), they are "valid" and should be imported into LLVM IR dialect. This
PR implements that by using an indirect call to represent it.
Translation already works nicely and outputs the same source llvm IR
file.

The error is now a warning, the tests in
`mlir/test/Target/LLVMIR/Import/import-failure.ll` already use `CHECK`
lines, so no need to add extra diagnostic tests.

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.

Getting in touch

Join the LLVM Discourse forums, Discord chat, LLVM Office Hours or Regular sync-ups.

The LLVM project has adopted a code of conduct for participants to all modes of communication within the project.
