build(meson): warn/fail on 32-bit machines (#2181)

Browse Source 
On 32-bit Windows, meson setup fails with an unclear error:

    meson.build:25:16: ERROR: Could not get define 'CPPHTTPLIB_VERSION'

The actual problem is that httplib.h #errors out.

Have the Meson logic explicitly check for a 32-bit host and warn or error,
matching the check in httplib.h.  Phrase the Windows error in a way that
triggers WrapDB CI's unsupported architecture check.
