utils: drop cmake version check

[compnerd]

There is no guarantee that cmake is available in the path. CMake may be provided through VS or the VS Build Tools, in which case, you must be in a VSDevCmd environment to invoke cmake. This adds quite a bit of complexity for little gain as the projects will check of the minimum version required (cmake_minimum_required).

@swift-ci please smoke test

Good point. I have no strong opinion on it, but if we remove this check, we might want to raise the cmake_minimum_required version in the top-level swift project from 3.19 to 3.28, because this is what swift-inspect requires

swift/tools/swift-inspect/CMakeLists.txt

Line 1 in ee9317a

cmake_minimum_required(VERSION 3.28)

FYI: We did have version checks like this before #77948 here: 6ca7ed6

@weliveindetail swift-inspect is built as a standalone project, not part of the Swift toolchain build, so the top level CMake version check doesn't impact it.

Yeah, I think that I would rather make things unconditional if possible.

@compnerd Yes, just saying that it's suboptimal to bail out so late in the build process due to an insufficient CMake version. That was the intention of the early check, but ithat's nice-to-have. If it causes issues, let's drop it.
