[BUG] Make table size adjustable according to table rows and columns

[ananzh]

Description

Auto-resized issue is caused by we have a central discover context created useSearch.
When it is updated, both panel and canvas which use useDiscoverContext will render.
The update on panel will trigger useSearch and cause canvas render before update is done.
Therefore when table might not be fully re-rendered and just use the current table space.
It appears that the main challenge is ensuring that DiscoverTable fully re-renders when the rows changes.

• This PR uses the length of the rows and a combination of last column that uniquely identify the state of the rows as the key.
• The last column name is helpful to make sure add/remove column will trigger fully re-render. For example, since _source takes multiple lines so we will see extra empty space at the bottom when we add a column. Since add/remove column always update last one, by add last column name as a key, we won't see extra space by fully re-render.

We could do more optimization after 2.12.

• investigate whether we have to call fetch in use_search when add/remove a column
• investigate whether we could not reload panel with canvas
• breaking down histogram and table fetch: [Data Explorer][Discover 2.0] Break down data fetch logic to multiple data streams or use Expression for histogram #4851

There are two functional tests broken by reload. If we think this could be a tmp fix, I could fix the tests as well.
