TidbCluster: disable evict leader for TiKV EBS modification (#5826)

[ti-chi-bot]

This is an automated cherry-pick of #5826

What problem does this PR solve?

evict leader for TiKV may take a long time, and the performance drop without leader-eviction is very low.

So we decide to disable this leader-eviction behavior for TiKV EBS modification.

NOTE: do not upgrade TiDB Operator when some leader-eviction (with EBS modification, but do not include EBS size modification, ref #5101) is happening as after this PR no "remove evict-leader-scheduler" will be performed then some evict-leader-scheduler may be kept.

What is changed and how does it work?

Code changes

• Has Go code change
• Has CI related scripts change

Tests

• Unit test
• E2E test
• Manual test
