In commit v3.6.0-rc1~174^2 (Ninja: Honor CMAKE_NINJA_FORCE_RESPONSE_FILE
for compile rules, 2016-04-06), Ninja learned to look for
`CMAKE_NINJA_FORCE_RESPONSE_FILE` in the current scope or the
environment in order to force response file usage for all compilation
rules.
However, on Windows, the RC compiler goes through cmcldeps which does a
`replace(output, output + ".dep.obj")` on the command line. However,
with a response file (which we name `output + ".rsp"`), the response
file path is replaced instead causing the compiler to (correctly)
complain that the response file `output + ".dep.obj.rsp"` does not
exist.
What needs to happen is for cmcldeps to look through the response file,
replace *its* contents and place it in the `output + ".dep.obj.rsp"`
file.
Also add a test which actually compiles an RC file into a library and
executable for all generators on Windows and additionally test
`CMAKE_NINJA_FORCE_RESPONSE_FILE` for Ninja generators.
Fixes #16167.
