MSVC: Use -external:I flag without space to support Clang tools
Since commit f29e1874ad (Compiler/MSVC: use the `-external:I` flag for
system includes, 2020-05-19, v3.22.0-rc1~593^2) we use the new flag
followed by the include directory as a separate argument. Some versions
of `clang-cl` and `clang-tidy` do not support the flag unless the
include directory is attached to it, so use that form instead.
Fixes: #22979
