Subject: [PATCH] Windows: embed a manifest that declares longPathAware

With LongPathsEnabled set in the registry, Windows lets a program open
paths of 260 characters or more only if its manifest says longPathAware.
QElectroTech.exe so far carried the toolchain's default manifest. This one
repeats what the default declares (supported Windows versions, asInvoker)
and adds longPathAware. MSVC takes the .manifest as a source; MinGW gets it
through a small resource file.

Follow-up to #1178 (symbols in deep folders).
