configure: add --disable-docs flag

Browse Source 
Building man pages from curldown sources now requires perl. Add a
--disable-docs flag to configure to enable building and installing
without documentation where perl is not available or man pages are not
required. This is selected automatically (with a warning) when perl is
not found by configure.

Fixes #12832
Closes #12857
