pw_cpu_exception_cortex_m: Remove packed attributes from structs

Removes the packed attributes from the CpuState structs to ensure they
can be safely directly accessed without a risk of unaligned access to
satisfy `-Werror=address-of-packed-member`.

To ensure it continues to be correct compared to our assembly,
static_asserts were added to verify there is no unexpected padding.
