Right now in case of DETACH/ATTACH there can be a window when after the
table had been DETACH'ed someone will still use it, the common example
here is MVs handling.
It happens because TableExclusiveLockHolder does not guards the
shard_ptr of the IStorage, and so if someone holds it, then it can use
it. So if ATTACH will be done for this table then, you can have multiple
instances of it.
It is not possible for DROP, because before using a table, you should
lock it and after table had been DROP'ed you cannot lock it anymore.
So let's do the same for DETACH.

Converted usage of CH-custom bit_cast to std::bit_cast if possible, i.e.
when
sizeof(From) == sizeof(To).
(The CH-custom bit_cast is able to deal with sizeof(From) != sizeof(To).)
Motivation for this came from #42847 where it is not clear how the
internal bit_cast should behave on big endian systems, so we better
avoid that situation as much as possible.
- lots of static_cast
- add safe_cast
- types adjustments
- config
- IStorage::read/watch
- ...
- some TODO's (to convert types in future)
P.S. That was quite a journey...
v2: fixes after rebase
v3: fix conflicts after #42308 merged
