feat: added max/resp_body_bytes attr to logger plugins

[janiussyafiq]

Description

Synchronize max/resp body size attributes to other logger plugins, just like the PR here: #11133. Also added test case to http-logger similar to https://github.com/apache/apisix/blob/3ccbfd6e4678834585af3b4a7198982c5d020034/t/plugin/kafka-logger-large-body.t, to ensure robust and correct use of the attributes, preventing bugs in the future. Since the test is passing, no need to add test cases for each logger. Here is the list of all logger plugins that are updated:

• http-logger
• skywalking-logger
• tcp-logger
• rocketmq-logger
• udp-logger
• clickhouse-logger
• syslog
• sls-logger
• file-logger
• loggly
• elasticsearch-logger
• tencent-cloud-cls
• loki-logger

Below logger might not be compatible hence attributes not getting added:

• log-rotate
• error-log-rotate
• google-cloud-logging
• splunk-hec-logging
• lago

Also, haven't updated Chinese documentation.

Which issue(s) this PR fixes:

Fixes #12130

Pull request overview

This PR propagates request/response body size limiting (max_req_body_bytes, max_resp_body_bytes) across multiple logger plugins and adds an http-logger regression test to ensure large bodies are truncated correctly when body logging is enabled.

Changes:

• Add max_req_body_bytes / max_resp_body_bytes schema attributes (default 524288) to multiple logger plugins and update docs accordingly.
• Add access-phase request body pre-reading for logger plugins when include_req_body is enabled (and optionally gated by include_req_body_expr).
• Add a new t/plugin/http-logger-large-body.t test covering truncation behavior and schema validation for max body byte settings.
