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.

Pigweed

Pigweed is an open source collection of embedded-targeted libraries–or as we like to call them, modules. These modules are building blocks and infrastructure that enable faster and more reliable development on small-footprint MMU-less 32-bit microcontrollers like the STMicroelectronics STM32L452 or the Nordic nRF52832.
