libtiff upgrade to version 4.6.0 (#25096) 
* libtiff upgrade to version 4.6.0

* fix tiffvers.h cmake generation

* temp: force build 3rd party deps from source

* remove libport.h and spintf.c

* cmake fixes

* don't use tiff_dummy_namespace on windows

* introduce numeric_types namespace alias

* include cstdint

* uint16_t is not a numeric_types type

* fix uint16 and uint32 type defs

* use standard c++ types

* remove unused files

* remove more unused files

* revert build 3rd party code from source
