* Be more strict when looking for the desired VS

On systems where VS 2017 and VS 2019 are available, the starter script
may choose VS 2019 if vc15 is requested.  The documentation on vswhere
isn't particularly clear regarding the -version parameter, but it
states that a version range is expected.  Therefore we change the
shell setup script accordingly.

* Remove break constructs

These had been introduced to cater to multiple found VS installations,
to only use the first one.  Since the ranges are supposed to find only
a single installation, and since apparently the order of multiple
findings is not guaranteed, we remove the break constructs for better
readability of the source code.
