make two members const

there are few other instances in gstevent and gstmessage. 

I'll change GstEventQuarks and GstMessageQuarks after freeze together with those in gstpad.c

and another one in gstformat.c
struct _GstFormatDefinition

and in gstquery.h
struct _GstQueryTypeDefinition

those last two would break API and cannot be changed.

indeed, moved the last two to #339744

        * gst/gstevent.c: (gst_event_get_type):
        * gst/gstmessage.c:
        * gst/gstpad.c: (gst_pad_chain_unchecked), (gst_pad_chain),
        (gst_pad_push):
        constify quark registration strings. Fixes #344115
        Avoid unneeded type checking is _pad_push() by internally
        calling gst_pad_chain_unchecked().
