gh-115119: Switch Windows build to mpdecimal external (GH-115182)

Browse source 
This includes adding what should be a relatively temporary
`Modules/_decimal/windows/mpdecimal.h` shim to choose between `mpdecimal32vc.h`
or `mpdecimal64vc.h` based on which of `CONFIG_64` or `CONFIG_32` is defined.

/* Windows mpdecimal.h shim
*
* Generally, the mpdecimal library build will copy the correct header into
* place named "mpdecimal.h", but since we're building it ourselves directly
* into _decimal.pyd, we need to pick the right one.
