Add an explicit `<Natvis>` element in VS project files for `*.natvis`
files. These enable custom debug visualizers for project-specific
types.
Fixes#16043.
Use `sysconf(_SC_ARG_MAX)` wherever `_SC_ARG_MAX` is available instead
of hard-coding an incomplete list of operating systems that implement
it. In particular, it is available on BSD platforms that were not
previously listed.
Commit v3.6.0-rc1~174^2~1 (cmGlobalNinjaGenerator: Clarify logic for
forcing use of response files, 2016-04-06) started using negative
command line length values to represent forced use of response files but
forgot to update `calculateCommandLineLengthLimit()` accordingly. Teach
it to return `0` instead of `-1` when no limit is computed from the
system to avoid forcing response files.

Document these variables.
Change our convention for setting these variables from:
set(CMAKE_EXE_LINKER_FLAGS_INIT "...")
to
string(APPEND CMAKE_EXE_LINKER_FLAGS_INIT " ...")
so that any value previously set by a toolchain file will be used.
