[lldb] Support swiftlang tests with nested make invocations on Windows

[weliveindetail]

Following the upstream patches llvm#112342 and llvm#112360, we can roll out the fix for the swiftlang-specific tests.

Haha, this is how to get attention. To all the new reviewers: sorry for the noise, this is still a boring patch.

@swift-ci please test

The Linux build failed, because the just-built Swift compiler hits an assertion in the standard library during CMake's "Check for working Swift compiler" step in swift-corelibs-libdispatch:

swift-frontend: /home/build-user/swift/stdlib/public/runtime/AccessibleFunction.cpp:110:
void swift::addImageAccessibleFunctionsBlockCallbackUnsafe(const void *, const void *, uintptr_t):
Assertion `size % sizeof(AccessibleFunctionRecord) == 0 && "accessible function section not a multiple of AccessibleFunctionRecord"' failed.

This is unrelated to my patch. LLDB built fine and testing didn't start yet. Previous premerge checks failed for the same reason since #9442

Edit: All still-visible failures here happened for the same reason: https://ci.swift.org/view/Swift%20rebranch/job/oss-swift-rebranch-lldb-linux-ubuntu-22_04/

@swift-ci please test Linux Platform

Thanks. Rebranch linux is still broken.

@swift-ci please test Linux Platform

Perfect, I think this can land any time.
