Fix typos: 'auxilliary' to 'auxiliary' and multiple other typos

Corrects multiple instances of the misspelling 'auxilliary' to 'auxiliary' across code, comments, and documentation in XCOFF-related files. Also fixes minor typos such as 'unit64_t' to 'uint64_t' and 'expect' to 'except', and updates a mask name from 'IsGlobaLinkageMask' to 'IsGlobalLinkageMask'.
