Wcast-align=strict results in cast alignment errors with EDS build

Checklist (Please check before submitting)

• I reviewed the Contributing Guide.
• I performed a cursory search to see if the bug report is relevant, not redundant, nor in conflict with other tickets.

Describe the bug
Enabling -Wcast-align=strict with EDS build enabled results in cast alignment warnings due to EDS defined structures having different alignment than the native structures, specifically with CFE_SB_Buffer_t and EdsNativeBuffer_CFE_HDR_CommandHeader_t (as compared to CFE_MSG_CommandHeader_t for non-EDS builds)

To Reproduce
Steps to reproduce the behavior:

1. Checkout techdev-multitarget-bundle
2. add -Wcast-align=strict to arch_build_custom.cmake compile options
3. remove -Werror to see all the warnings
4. make native_eds.compile

Expected behavior
No cast alignment warnings
