Ref: https://github.com/redis/redis/pull/12760
### Description
#### Fixes compatibilty of PlaceholderKV cluster (7.2 - extensions
enabled by default) with older Redis cluster (< 7.0 - extensions not
handled) .
With some of the extensions enabled by default in 7.2 version, new nodes
running 7.2 and above start sending out larger clusterbus message
payload including the ping extensions. This caused an incompatibility
with node running engine versions < 7.0. Old nodes (< 7.0) would receive
the payload from new nodes (> 7.2) would observe a payload length
(totlen) > (estlen) and would perform an early exit and won't process
the message.
This fix introduces a flag `extensions_supported` on the clusterMsg
indicating the sender node can handle extensions parsing. Once, a
receiver nodes receives a message with this flag set to 1, it would
update clusterNode new field extensions_supported and start sending out
extensions if it has any.
This PR also introduces a DEBUG sub command to enable/disable cluster
message extensions `process-clustermsg-extensions` feature.
Note: A successful `PING`/`PONG` is required as a sender for a given
node to be marked as `extensions_supported` and then extensions message
will be sent to it. This could cause a slight delay in receiving the
extensions message(s).
### Testing
TCL test verifying the cluster state is healthy irrespective of
enabling/disabling cluster message extensions feature.

Small changes to the log messages printed during startup and shutdown,
for Valkey branding.
SERVER_NAME is replaced by verbatim "Valkey" in one place, because
SERVER_NAME expands to "valkey" in lowercase. (Should we introduce
another macro that expands to "Valkey"?)

These were flagged on the 7.2 build system, which is using the old spell
check. I think we should consider re-adding it as it missed some typos.

Adds a new make variable called `USE_REDIS_SYMLINKS`, with default value
`yes`. If yes, then `make install` creates additional symlinks to the
installed binaries:
* `valkey-server`
* `valkey-cli`
* `valkey-benchmark`
* `valkey-check-rdb`
* `valkey-check-aof`
* `valkey-sentinel`
The names of the symlinks are the legacy redis binary names
(`redis-server`, etc.). The purpose is to provide backward compatibility
for scripts expecting the these filenames. The symlinks are installed in
the same directory as the binaries (typically `/usr/local/bin/` or
similar).
Similarly, `make uninstall` removes these symlinks if
`USE_REDIS_SYMLINKS` is `yes`.
This is described in a note in README.md.
Fixes#147

This commit does not remove redis.call/pcall just yet. It also does not
rename Redis in error messages such as "Please specify at least one
argument for this redis lib call". This allows users to maintain full
backwards compatibility while introducing an option to use server.call
for new code.
I verified that the unit tests pass. Also manually verified that the
redis-server responds to server.call invocations within lua scripting.
Also verified that function registration works as expected.

This commit updates the following fields:
1. server_version -> valkey_version in server info. Since we would like
to advertise specific compatibility, we are making the version specific
to valkey. servername will remain as an optional indicator, and other
valkey compatible stores might choose to advertise something else.
1. We dropped redis-ver from the API. This isn't related to API
compatibility, but we didn't want to "fake" that valkey was creating an
rdb from a Redis version.
1. Renamed server-ver -> valkey_version in rdb info. Same as point one,
we want to explicitly indicate this was created by a valkey server.

Fix#146
Removed REDISMODULE_ prefixes from the core source code to align with
the new SERVERMODULE_ naming convention. Added a new 'redismodule.h'
header file to ensure full backward compatibility with existing modules.
This compatibility layer maps all legacy REDISMODULE_ prefixed
identifiers to their new SERVERMODULE_ equivalents, allowing existing
Redis modules to function without modification.

New info information to be used to determine the valkey versioning info.
Internally, introduce new define values for "SERVER_VERSION" which is
different from the Redis compatibility version, "REDIS_VERSION".
Add two new info fields:
`server_version`: The Valkey server version
`server_name`: Indicates that the server is valkey.
Add one new RDB field: `server_ver`, which indicates the valkey version
that produced the server.
Add 3 new LUA globals: `SERVER_VERSION_NUM`, `SERVER_VERSION`, and
`SERVER_NAME`. Which reflect the valkey version instead of the Redis
compatibility version.
Also clean up various places where Redis and configuration was being
used that is no longer necessary.
