[tint] Migrate CMake build over to generated files/deps

Add a `BUILD.cmake.tmpl` template file to emit CMake build files and
target dependency information.

Rename TINT_BUILD_SAMPLES to TINT_BUILD_CMD_TOOLS. The 'tint' executable
is used more as a command-line interface than a sample.

Update the root tint CMakeLists.txt file to use this.
