Clang: Use -imsvc flag without space to support Clang tools

Browse Source 
Since commit bb61c2d024 (Clang: use -imsvc for system include dirs when
running on Windows, 2020-09-16, v3.19.0-rc1~162^2) we use the `-imsvc`
flag followed by the include directory as a separate argument.  Some
versions of `clang-tidy` do not support the flag unless the include
directory is attached to it, so use that form instead.

A similar fix was made by commit 3a8b6653dc (MSVC: Use -external:I flag
without space to support Clang tools, 2022-01-11, v3.22.2~8^2).

Fixes: #23517
