Add CFI-ICALL to needed PipeWire methods

Adds missing RTC_NO_SANITIZE("cfi-icall") attributes to a few needed
functions for PipeWire initialization. These are methods that call (or
call methods that end up inlined and call) function pointers as a result
of dlopen'ing a lib. For ShareScreencastStream, the generated
InitializeStubs method appears to trigger this; while the egl_dmabuf
destructor appears to need this due to the EglDestroyContext and
EglTerminate calls that it makes.
