Require ICU ≥ 50.1

Given that ICU is a set of lively developed libraries, that ICU 50.1
has been released on 2012-11-05, and PHP 7.4 is scheduled to be
released seven years after it, we consider it appropriate to ditch
these legacy versions.

Particularly, that would be a reasonable groundwork to implement part
two of the “Deprecate and remove INTL_IDNA_VARIANT_2003” RFC[1], namely
to default idn_to_ascii()'s and idn_to_utf8()'s $variant parameter to
INTL_IDNA_VARIANT_UTS46, which is not defined in ICU < 4.6.

See also the related discussion on internals@[2].
