[llvm] [llvm] remove unusable llvm.spec.in (PR #96825)

[Konrad Kleine via llvm-commits]

https://github.com/kwk created https://github.com/llvm/llvm-project/pull/96825

The `llvm.spec.in` is turned into `llvm.spec` through cmake. The spec file's `%build` section runs `./configure` which has been deprecated since 2016 (See e49730d4baa8443ad56f59bd8066bf4c1e56ea72).

-%description
-LLVM is a compiler infrastructure designed for compile-time, link-time, runtime,
-and idle-time optimization of programs from arbitrary programming languages.
-LLVM is written in C++ and has been developed since 2000 at the University of
-Illinois and Apple. It currently supports compilation of C and C++ programs,
-using front-ends derived from GCC 4.0.1. A new front-end for the C family of
-languages is in development. The compiler infrastructure
-includes mirror sets of programming tools as well as libraries with equivalent
-functionality.
