VS: Add special case for '-T version=14.29.16.11' under VS 16.11

Extend the table of special cases from commit 58a50a3a (VS: Fix '-T
version=14.28' under VS 16.9, 2021-03-11, v3.19.7~1^2~1) and updated by
commit a60141fe (VS: Add special case for '-T version=14.29.16.10'
under VS 16.10, 2021-05-27, v3.20.4~11^2).  Add a special case for the
name VS 17 will use for VS 16.11's default toolset, so that it can be
used with VS 16.11 too.
