Meta: Add option to disable Kernel Address Sanitizer

Browse source 
By default we enable the Kernel Undefined Behavior Sanitizer, which
checks for undefined behavior at runtime. However, sometimes a developer
might want to turn that off, so now there is a easy way to do that.

There are some optional features that can be enabled during compilation that are intended to help with specific types of development work or introduce experimental features. Currently, the following build options are available:
- `ENABLE_ADDRESS_SANITIZER` and `ENABLE_KERNEL_ADDRESS_SANITIZER`: builds in runtime checks for memory corruption bugs (like buffer overflows and memory leaks) in Lagom test cases and the kernel, respectively.
- `ENABLE_KERNEL_UNDEFINED_SANITIZER`: builds in runtime checks for detecting undefined behavior in the kernel.
- `ENABLE_KERNEL_COVERAGE_COLLECTION`: enables the KCOV API and kernel coverage collection instrumentation. Only useful for coverage guided kernel fuzzing.
- `ENABLE_USERSPACE_COVERAGE_COLLECTION`: enables coverage collection instrumentation for userspace. Currently only works with a Clang build.
- `ENABLE_MEMORY_SANITIZER`: enables runtime checks for uninitialized memory accesses in Lagom test cases.
