Use cmake_dependent_option for options that require IREE_BUILD_COMPILER. (#7985)
Docs:
* https://cmake.org/cmake/help/latest/module/CMakeDependentOption.html
* https://cmake.org/cmake/help/latest/command/option.html
These options will now all automatically be forced to `OFF` when `IREE_BUILD_COMPILER` is `OFF`, rather than use previously cached/configured values.
