String changes for some SIM switch confirmation dialogs
These are changes for strings used in two scenarios:
-When switching which SIM is used for mobile data. This is an update to
some existing strings.
-Enabling an eSIM when another one is already enabled (so the first one
will need to be disabled). These are new strings.

Test: compile, plus manual (run a device in DSDS mode, go to details for
SIM that isn't currently used for mobile data, and tap on mobile data
switch)
