[eclipse-pmc] PMC API request: two new constructors in WorkbenchStatusDi

[Kevin McGuire <Kevin_McGuire@xxxxxxxxxx>]

GOALS/BENEFITS:

WorkbenchStatusDialogManager was introduced in 3.4 but the constructors
took a Shell argument that they should not have. The shell is now being
ignored in WorkbenchStatusDialogManager due to other fixes already released.

This proposal is simply to:

1) Add new constructors that don't take the shell
so people can the "correct" API
2) Mark the two existing constructors as deprecated (as much as it pains
us
to do so in a newly released class).

ASSOCIATED BUGS:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=231163


RISKS:
None, this is new API in a new class.
Also the two early adopters that we know of of the
new status handling support aren't using it.

PERFORMANCE IMPACT:
none
