EQL: Fix syntax for event type (#63169) (#63194)
Event type is actually a string value for event.category which can
contain any kind of characters, or start with a digit, which currently
is not supported, so we introduce the possibility to be able to use the
usual syntax of " and """ for strings and raw strings.

Make the grammar a bit cleaner by using the identifier only where it's
actually an identifier in terms of query scemantics.

Fixes: #62933
