split Timestamp tests off of #19504

[jbrockmendel]

There is de-duplication/parametrization etc to be done, but that should wait until the tests are collected because we'll have to re-do it then anyway.

this is fine, assuming you are going to completely destruct pandas/tests/tseries/test_timezones and put the tests in the appropriate places ?

Most of it will go into Timestamp/DatetimeIndex/...-specific modules. There are some pieces that are more directly testing tslibs.timezones/tslibs.conversions, which can either stay in tests.tseries or go into a new tests.tslibs.
