Subject: [PATCH] [flang][msvc] Add explicit function template argument to
 applyLamda. NFC.

Like in D87961, msvc has difficulties deducing the template argument. The error message is:
```
expr-parsers.cpp(383): error C2672: 'applyLambda': no matching overloaded function found
```
Explicitly pass the first template argument to help it.

This patch is part of the series to make flang compilable with MS Visual Studio <http://lists.llvm.org/pipermail/flang-dev/2020-July/000448.html>.
