Konsole: CSI 2J: Do not append current screen to history
Summary:
This behavior is present in e.g. xterm and linux console.
Currently when using CSI 2J escape sequence, screen contents are
appended to scrollback (including bottom empty lines). This is breaking
`clear` command, which replaces scrollback with current screen contents.
BUG: 384218
Test Plan:
* Start Konsole with a shell
* `clear`
**Expected result:**
Cleared display, empty scrollback.
**Actual result:**
Cleared display, but scrollback contains previous display contents.
---
* Start Konsole with a shell
* seq 1000
* `echo -ne '\033[2J`
**Expected result:**
Cleared display, numbers in last scrollback lines.
**Actual result:**
Cleared display, but scrollback contains previous display contents
(i.e. shell prompt in last lines)
