  [lldb][windows] fix cross DLL file descriptor lookup crash (#195855)

On Windows, file descriptors are only valid in the same DLL: they are
really just handles mapped to an index in a table in the CRT. Calling a
liblldb method with a file descriptor from lldb-dap will cause the
program to crash. See
https://github.com/llvm/llvm-project/issues/193971.

This patch fixes the issue by refactoring the `NativeFile` constructors
so that they no longer try to convert `FILE` types to handles through
the CRT lookup table.

(cherry picked from commit 176dff4a5afdaa7f8ca040b4e06c96ef918e8a22)
