Extended value patterns inventory

[jsmorph]

Here's an initial attempt at an inventory of various "extended" pattern matching capabilities. Look about right?

Extended pattern type	Notes	Implementations
string equality		EB, ER, Q
number equality	Representation challenges	EB, ER, Q
Boolean equality		EB, ER, Q
anything-but		EB, ER, Q
exists		EB, ER, Q
shellstyle		Q
prefix		EB, ER, Q
suffix	Via shellstyle in Q	EB, ER
wildcard	Multiple * supported in EB, ER	EB, ER
cidr		EB, ER
"normal" $or		EB, ER
"parallel" $or		EB, ER
numeric inequalities		EB, ER
numeric equality		EB, ER

I broke out some types (like numeric and implicit equals) perhaps unnecessarily.

Couple of comments

• Suffix via shell-style shouldn't count since there's already shell-style row.
• EventBridge doesn't support wildcards yet.

Also, there are some additional reserved pattern names that can be included here as not supported by any https://github.com/aws/event-ruler/blob/main/src/main/software/amazon/event/ruler/Constants.java#L44.
