QL: case sensitive support in EQL (#56404) (#56597)

* QL: case sensitive support in EQL (#56404)
* adds a generic startsWith function to QL
* modifies the existent EQL startsWith function to be case sensitive
aware
* improves the existent EQL startsWith function to use a prefix query
when the function is used in a case sensitive context. Same improvement
is used in SQL's newly added STARTS_WITH function.
* adds case sensitivity to EQL configuration through a case_sensitive
parameter in the eql request, as established in #54411.
The case_sensitive parameter can be specified when running queries
(default is case insensitive)

(cherry picked from commit ee5a09ea840167566e34c28c8225dc38bc6a7ae8)

--------------------------------------------------
*Input*:
<1> string expression
<2> string expression
*Output*: boolean value
*Description*: Returns `true` if the source expression starts with the specified pattern, `false` otherwise. The matching is case sensitive.
If either parameters is `null`, the function returns `null`.
