Fix setting of off-by-default cmake options

Browse Source 
An enclosing CMake project should be able to set the
off-by-default CMake options in SPIRV-Tools by just doing:
  set(SPIRV_SKIP_EXECUTABLES ON)
instead of
  set(SPIRV_SKIP_EXECUTABLES ON CACHE BOOL "" FORCE)

Also, fix the SPIRV_WARN_EVERYTHING so it understands which options
to send to Clang vs. GCC.

Note: With SPIRV_WARN_EVERYTHING enabled, the code doesn't
compil with either Clang or GCC.

The following CMake options are supported:
* `SPIRV_COLOR_TERMINAL=ON` - Enables color console output, enabled by default.
* `SPIRV_SKIP_EXECUTABLES=ON` - Build only the library, not the command line
tools. This will also prevent the tests from being built.
* `SPIRV_USE_SANITIZER=<sanitizer>` - On UNIX platforms with an appropriate
version of `clang` this option enables the use of the sanitizers documented
* `SPIRV_COLOR_TERMINAL={ON|OFF}`, default `ON` - Enables color console output.
* `SPIRV_SKIP_EXECUTABLES={ON|OFF}`, default `OFF`- Build only the library, not
the command line tools. This will also prevent the tests from being built.
* `SPIRV_USE_SANITIZER=<sanitizer>`, default is no sanitizing - On UNIX platforms
with an appropriate version of `clang` this option enables the use of the
sanitizers documented
[here](http://clang.llvm.org/docs/UsersManual.html#controlling-code-generation).
This should only be used with a debug build. Disabled by default.
* `SPIRV_WARN_EVERYTHING=OFF` - On UNIX platforms enable the `-Weverything`
compiler front end option, disabled by default.
* `SPIRV_WERROR=ON` - Forces a compilation error on any warnings encountered by
enabling the compiler-specific compiler front-end option, enabled by default.
This should only be used with a debug build.
* `SPIRV_WARN_EVERYTHING={ON|OFF}`, default `OFF` - On UNIX platforms enable
more strict warnings. The code might not compile with this option enabled.
For Clang, enables `-Weverything`. For GCC, enables `-Wpedantic`.
See [`CMakeLists.txt`](CMakeLists.txt) for details.
* `SPIRV_WERROR={ON|OFF}`, default `ON` - Forces a compilation error on any
warnings encountered by enabling the compiler-specific compiler front-end
option.
