Instead of "fixing" the alignment mask, return an error if the passed-in value is not actually a power of two. In ES this only gets passed from two possible sources: one is hardcoded (4) and the other is sourced from the ALIGN_OF macro.

Describe the contribution
Instead of "fixing" the alignment mask, return an error if the passed-in value is not actually a power of two.
Fixes #1346
Testing performed
Build and sanity test CFE, run all unit tests
Expected behavior changes
Function will return
CFE_ES_BAD_ARGUMENTif the passed in parameter is not a power of two.System(s) tested on
Ubuntu 20.04
Additional context
This is an internal functions, and in ES this only gets passed from two possible sources: one is CDS, hardcoded as 4, and the other is sourced from the ALIGN_OF macro for generic memory pools.
The latter is platform-dependent but I've never seen a platform that aligns data on something other than a power of two boundary.
