Ninja: don't use shell when cmake is called directly

When linking with cmake and vs_link_* the command line
could be too long for cmd.exe, which needs not to be
called in this case. (was not cached by a test)

Introduce rules which don't use the shell and use this
rule when there are no pre or post step.

For free we get a small speedup, because cmd is then
not called.

Also be more accurate when estimating the
command line length.
