We want to generate debug information even in the release builds of the
libraries in order to allow debugging of the programs using them. This is
especially important for the DLLs but do it for the static release build too
for consistency.
This also almost fixes the constant rebuilding of the entire solution which
happened because the PDBs, supposed to be generated by linker, were not found
because they were not actually created as the debug information wasn't there.
See #15780.
