SET is a R+W command, because it can also do `GET` on the data.
SET without GET is a write-only command.
SET with GET is a read+write command.
In #9974, we added ACL to let users define write-only access.
So when the user uses SET with GET option, and the user doesn't
have the READ permission on the key, we need to reject it,
but we rather not reject users with write-only permissions from using
the SET command when they don't use GET.
In this commit, we add a `getkeys_proc` function to control key
flags in SET command. We also add a new key spec flag (VARIABLE_FLAGS)
means that some keys might have different flags depending on arguments.
We also handle BITFIELD command, add a `bitfieldGetKeys` function.
BITFIELD GET is a READ ONLY command.
BITFIELD SET or BITFIELD INCR are READ WRITE commands.
Other changes:
1. SET GET was added in 6.2, add the missing since in set.json
2. Added tests to cover the changes in acl-v2.tcl
3. Fix some typos in server.h and cleanups in acl-v2.tcl

Summary of changes:
1. Rename `redisCommand->name` to `redisCommand->declared_name`, it is a
const char * for native commands and SDS for module commands.
2. Store the [sub]command fullname in `redisCommand->fullname` (sds).
3. List subcommands in `ACL CAT`
4. List subcommands in `COMMAND LIST`
5. `moduleUnregisterCommands` now will also free the module subcommands.
6. RM_GetCurrentCommandName returns full command name
Other changes:
1. Add `addReplyErrorArity` and `addReplyErrorExpireTime`
2. Remove `getFullCommandName` function that now is useless.
3. Some cleanups about `fullname` since now it is SDS.
4. Delete `populateSingleCommand` function from server.h that is useless.
5. Added tests to cover this change.
6. Add some module unload tests and fix the leaks
7. Make error messages uniform, make sure they always contain the full command
name and that it's quoted.
7. Fixes some typos
see the history in #9504, fixes#10124

This commit introduced a new flag to the RM_Call:
'C' - Check if the command can be executed according to the ACLs associated with it.
Also, three new API's added to check if a command, key, or channel can be executed or accessed
by a user, according to the ACLs associated with it.
- RM_ACLCheckCommandPerm
- RM_ACLCheckKeyPerm
- RM_ACLCheckChannelPerm
The user for these API's is a RedisModuleUser object, that for a Module user returned by the RM_CreateModuleUser API, or for a general ACL user can be retrieved by these two new API's:
- RM_GetCurrentUserName - Retrieve the user name of the client connection behind the current context.
- RM_GetModuleUserFromUserName - Get a RedisModuleUser from a user name
As a result of getting a RedisModuleUser from name, it can now also access the general ACL users (not just ones created by the module).
This mean the already existing API RM_SetModuleUserACL(), can be used to change the ACL rules for such users.
