MDEV-34860 Fix opt_hint_timeout.test for embedded; fix mariadb client

1. Disable opt_hint_timeout.test for embedded server. Make sure
the test does not crash even when started for embedded server.
Disable view-protocol since hints are not supported inside views.

2. Hints are designed to behave like regular /* ... */ comments:
   `SELECT /*+ " */ 1;` -- a valid SQL query
However, the mysql client program waits for the closing doublequote
character.
Another problem is observed when there is no space character between
closing `*/` of the hint and the following `*`:
   `SELECT /*+ some_hints(...) */* FROM t1;`
In this case the client treats `/*` as a comment section opening and
waits for the closing `*/` sequence.

This commit fixes all of these issues
