do not use shell integration for Python subshell if Python setting is…

… disabled (microsoft#24418)

Resolves: microsoft#24422

If the user has explicitly set their Python shell integration setting to
false,
then do not use shell integration inside the sub-shell (Python Terminal
REPL in this case),
regardless of upper shell integration status (Terminal shell integration
setting in vscode).

We should still be safe from manual installation of shell integration
with the setting
disabled(https://code.visualstudio.com/docs/terminal/shell-integration#_manual-installation)
since we are still reading the value of terminal.shellIntegration, and
looking at Python's shell integration setting first to begin with.
