This PR handles several aspects 1. Calls to RM_ReplyWithError from thread safe contexts don't violate thread safety. 2. Errors returning from RM_Call to the module aren't counted in the statistics (they might be handled silently by the module) 3. When a module propagates a reply it got from RM_Call to it's client, then the error statistics are counted. This is done by: 1. When appending an error reply to the output buffer, we avoid updating the global error statistics, instead we cache that error in a deferred list in the client struct. 2. When creating a RedisModuleCallReply object, the deferred error list is moved from the client into that object. 3. when a module calls RM_ReplyWithCallReply we copy the deferred replies to the dest client (if that's a real client, then that's when the error statistics are updated to the server) Note about RM_ReplyWithCallReply: if the original reply had an array with errors, and the module replied with just a portion of the original reply, and not the entire reply, the errors are currently not propagated and the errors stats will not get propagated. Fix #10180

When parsing an array type reply, ctx will be lost when recursively parsing its elements, which will cause a memory leak in automemory mode. This is a result of the changes in #9202 Add test for callReplyParseCollection fix

## Current state 1. Lua has its own parser that handles parsing `reds.call` replies and translates them to Lua objects that can be used by the user Lua code. The parser partially handles resp3 (missing big number, verbatim, attribute, ...) 2. Modules have their own parser that handles parsing `RM_Call` replies and translates them to RedisModuleCallReply objects. The parser does not support resp3. In addition, in the future, we want to add Redis Function (#8693) that will probably support more languages. At some point maintaining so many parsers will stop scaling (bug fixes and protocol changes will need to be applied on all of them). We will probably end up with different parsers that support different parts of the resp protocol (like we already have today with Lua and modules) ## PR Changes This PR attempt to unified the reply parsing of Lua and modules (and in the future Redis Function) by introducing...
