[Security][Network] Exclude glob-only (*) Index Pattern from map laye…

…rs (elastic#69736) (elastic#69824)

* Exclude glob-only (*) index pattern from map layers

This pattern is a special case that our map should ignore, as including
it causes all indexes to be queried.

* Ignore CCS glob pattern in our embedded map

Users may have this pattern for cross-cluster search, and it should
similarly be excluded when matching Security indexes.
