What problem does this PR solve?

Issue Number: close #40155

Problem Summary:

This is an automated cherry-pick of #40156

Telemetry can not be enabled by global variable when it's disabled in config file. Therefore we don't need to run telemetry related loops at all when telemetry is disabled from global config.

Same as #41147 but with merge conflicts fixed.

if config.GetGlobalConfig().EnableTelemetry {
// There is no way to turn telemetry on with global variable `tidb_enable_telemetry`
// when it is disabled in config. See IsTelemetryEnabled function in telemetry/telemetry.go

Is adding go func() here like this not changing the behaviour? Is this ok for a bugfix release?

Hm, it shouldn't affect any feature but just make initialization synchronous and speed up startup when connecting to telemetry server is blocked by network policy.

The reason to add go here was I realized that starting tidb-server takes about 20 seconds when the hosting environment doesn't have internet access.

But I think you are right. We should keep changes as small as possible for back port. I have reverted this according to the behavior in 6.1. PTAL
