sha1: fix compilation of WinHTTP backend#5174

When selecting the SHA1 backend, we only include the respective C implementation of the selected backend. But since commit bd48bf3 (hash: introduce source files to break include circles, 2019-06-14), we have introduced separate headers and compilation units for all hashes. So by not including the headers, we may not honor them to compute whether a file needs to be recompiled and they also will not be displayed in IDEs. Add the header files to fix this problem.
In commit bbf034a (hash: move `git_hash_prov` into Win32 backend, 2019-02-22), the `git_hash_prov`'s structure name has been removed in favour of its typedef'ed name. But as we have no CI that compiles with the WinHTTPS hashing backend right now, it wasn't noticed that the implementation that uses this struct wasn't changed correctly. Fix the struct type to make it compile again.
We currently have no job that compiles libgit2 with the WinHTTP backend for SHA1. Due to this, a compile error has been introduced and not noticed for several months. Change the x86 MSVC job to use the HTTPS backend for SHA1. The x86 job was chosen with no particular reason.

I was hesitant to do this, but I think that it's the right thing, because we'll want to ensure that we don't break the hash backend selection for when we tackle sha256. |

With my HTTPS refactorings, I've introduced breakage to the WinHTTP SHA1 backend which went unnoticed. This PR fixes the error and changes one MSVC CI job to compile with "-DUSE_SHA1=HTTPS".
Fixes #5165
