[llvm] [Sanitizer] Use DK_OptimizationRemarkMissed for DiagnosticInfoInstrumentation. (PR #106356)

[via llvm-commits]

https://github.com/skc7 created https://github.com/llvm/llvm-project/pull/106356

#99439 DiagnosticInfoInstrumentation initializes DiagnosticInfo with DK_Linker. 
Diagnostic message reporting here for instrumentation matches with optimisation remark rather than DK_Linker.
This PR replaces DK_LINKER with DK_OptimizationRemarkMissed.
