[flang][windows] Add option to link against specific MSVC CRT (#70833)

DavidTruby · web-flow · commit cf1e3420b014 · 2023-11-10T16:13:49.000Z
Currently flang's runtime libraries are only built for the specific CRT
that LLVM itself was built against. This patch adds the cmake logic for
building a separate runtime for each CRT configuration and adds a flag
for selecting a CRT configuration to link against.
