For privacy reasons, time functions use GMT, to avoid logs leaking
timezones. It'd make more sense to use localtime for wallet output
(which are not logged by default), but that adds inconsistencies
which can also be confusing. So add a Z suffix for now to make it
clear these are not local time.
Unrelated, but similar code-wise to #8643. There is a check in `DNSResolver` which automatically fails to resolve hostnames which do not contain the `.` character. This PR removes that check.
As of OpenSSL 3.0, `SHA256_Init`, `SHA256_Update`, and `SHA256_Final`
are deprectaed in favor of the higher-level `EVP_*` class of functions.
This causes compiler warnings, and sooner or later, will cause build
errors as these functions are excluded from distro headers.
Also add some documentation.
Actions:
1. Remove unused functions from misc_os_dependent.h
2. Move three remaining functions, get_gmt_time, get_ns_count, and get_tick_count into time_helper.h
3. Remove unused functions from time_helper.h
4. Refactor get_ns_count and get_internet_time_str and get_time_interval_string
5. Remove/add includes as needed

In some contrived case, it might theoretically be the case that
destroy is called from another thread, which would modify the
threads array from two threads.
