YT-21233: Adjust (To/From)ErrorAttributeValue CPOs, revert ConvertTo becoming CPO, move TErrorCode and TError to library/cpp/yt/error

\[nodiff:caesar\]

List of changes:

 1) Make `ConvertTo` a normal function again (basically, a revert of previous change). It turned out to be very inconvenient entry point

 2) Introduce concept for "Primitive types" which are handled without yt/core module. Please note that inclusion of core **does not** affect work with primitive types (otherwise we would be facing and ODR violation). These are numerics, duration, instant, string-like objects and guid

 3) Introduce `FromErrorAttributeValue` which is a substitute to `ConvertTo` with special behavior (see below)

 4) Scheme for (de-)serialization has changed:

    1) Primitive types are handled via `ConvertToTextYsonString` and `ConvertFromTextYsonString`

    2) Other types are not supported without yt/core. Otherwise `ConvertToYsonString(value, EYsonFormat::Text)` used for serialization and `ConvertTo<T>(value)` for deserialization.

 5) New format of attribute value storage allows to not care about concrete type of the attribute (text yson strings can be detected since they start with `\"` and deserialized so are text yson bools, everything else is already human readable). This drops dependency on `TTokenizer`

 6) Some small parts (e.g. enums or constants or aliases) of yt/core/misc files were moved to library/cpp/yt/\* locations and re-included to drop dependencies of stripped\_error on them

 7) `TErrorAttributes` is now a simple hash map instead of a handle to `IAttributeDictionary`

 8) `ExtractFromAttributes` weak symbol is finally moved to library/cpp/yt/error due to point 9 allowing to fully drop dependency on `IAttributeDictionary`. Combined with point 7 this drops dep on yt/core/ytree altogether

 9) Moved `TErrorCode` to library/cpp/yt/error. There is a logger there which forces dep on library/cpp/yt/logging. It is not required really, and can be later removed

10) Moved `TError` with format and macroes to library/cpp/yt/error. It still (and probably forever will) depend on yson.

What can be done next: Switch TYsonString to TString and move ConvertTo/FromTextYsonString to library/cpp/yt/error. This would remove dep on library/cpp/yt/yson\_string
