This introduces two new macros: PW_ASSERT() and PW_DASSERT(). These exist to offer a lightweight assert that is safe to use in headers and is safe for constexpr. Most of the time, these macros should not be used, and instead the PW_CHECK() and PW_DCHECK() variants used instead. Other changes: - Renames PW_ASSERT_ENABLE_DCHECK to PW_ASSERT_ENABLE_DEBUG, to reflect that the setting applies to both PW_CHECK and PW_ASSERT. - Updates Roadamp & Status documentation sections Testing: Since currently it is not possible to test the PW_ASSERT macros due to needing to swap the backend, this is manually tested by flipping the #if in pw_assert/light_test.cc to 1, and verifying that it crashes as expected.
