Enable KQL support for TSVB (elastic#26006)

* Use buildEsQuery for table, series and annotations

* Fix query test.

Using the buildEsQuery changed a bit the order of the must.bool array on the query

* Remove console.log

* Remove console.error and comment

* Fix wrong merge of PR elastic#26510

* Fix default/empty index_pattern

When the user save the visualization without configuring
manually an index_pattern, a default empty string is used
instead of the default pattern. This leads to an empty
visualization after the refactoring done in elastic#24832.
Now it will update the index_pattern field with the default
index pattern in visualize editor and on dashboard.

* Remove unnecessary wrapping query in an array

* Enable query bar on tsvb

* Remove unnecessary setDefaultIndexPattern

After fixing the null index pattern issue in kql
there is no need to use set the default index pattern
before rendering.

* fix(tsvb-server): Ignore query bar search on ignore_global_filters param

This commit mimic the behaviour of the ignore_global_filters currently used with lucene syntax:
if you enable the ignore_global_filter option on data or on annotations, data or annotations
are filtered out when using the filter bar and the search bar

* Disable showQueryBar
