bp #40718
## Proposed changes
Since [brpc's built-in
services](https://brpc.apache.org/zh/docs/builtin-services/buildin_services/)
will expose some internal server status, for security reasons, add the
parameter `enable_brpc_builtin_services` in `be.conf`. When the
parameter is false, this built-in service can be disabled.
Previously, when getting block from file cache, it may try to evict
lots of blocks to reserve capacity for lru cache. This operation may
take long time
while hold the lock, causing other operation blocked.
This PR add a new BE config `file_cache_max_evict_num_per_round`,
default is 1000, so that it will not hold lock for a long time.
## Proposed changes
Do `load_cache_info_into_memory()` asynchronously in a background thread
in `LRUFileCache::initialize()`.
When the cache is not ready, `LRUFileCache::get_or_set()` will return
the FileBlock which state is SKIP_CACHE.

1. revert https://github.com/apache/doris/pull/25097. we decide to rely
on OS. not maintain independent tzdata anymore to keep result
consistency
2. refactor timezone load. removed rwlock.
before:
```sql
mysql [optest]>select count(convert_tz(d, 'Asia/Shanghai', 'America/Los_Angeles')), count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) from dates;
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| count(convert_tz(cast(d as DATETIMEV2(6)), 'Asia/Shanghai', 'America/Los_Angeles')) | count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| 16000000 | 16000000 |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
1 row in set (6.88 sec)
```
now:
```sql
mysql [optest]>select count(convert_tz(d, 'Asia/Shanghai', 'America/Los_Angeles')), count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) from dates;
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| count(convert_tz(cast(d as DATETIMEV2(6)), 'Asia/Shanghai', 'America/Los_Angeles')) | count(convert_tz(dt, 'America/Los_Angeles', '+00:00')) |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
| 16000000 | 16000000 |
+-------------------------------------------------------------------------------------+--------------------------------------------------------+
1 row in set (2.61 sec)
```
3. now don't support timezone offset format string like 'UTC+8', like we
already said in
https://doris.apache.org/docs/dev/query/query-variables/time-zone/#usage
4. support case-insensitive timezone parsing in nereids.
5. a bug when parse timezone using nereids. should check DST by input,
but wrongly by now before. now fixed.
