[dpdk-dev] [PATCH v2] windows: minor build fixes

[Nick Connolly]

Meson versions >= 0.54.0 include support for handling /implib
with msvc link. Specifying it explicitly causes failures when
linking against the dll. Tested using Link 14.27.29112.0 and
Clang 11.0.0.

There were a number of changes to the way that import libraries
are handled between 0.47.1 and 0.54.0. Only make the change
for >= 0.54.0, leaving the behaviour unchanged for earlier
versions.
