Merge 11cf52e701 into f84341c574

All over oh-my-zsh I found plenty of functions and plugins
testing for the current OS or Platform.

For this PR I basically made simple is_[OS] functions that can be
used anywhere in plugins or oh-my-zsh code, instead of repeating these
over and over again.

I basically need such tests often, because my personal custom oh my zsh
additions run on macOS with Intel and M1 chips plus on different
linux's.

Functions:

- is_linux - the CPUTYPE env is linux*
- is_android - the CPUTYPE env is linux-android*
- is_netbsd the CPUTYPE env is netbsd*
- is_openbsd - the CPUTYPE env is openbsd*
- is_freebsd - the CPUTYPE env is freebsd*
- is_mac - the CPUTYPE env is darwin*
- is_mac_arm - it is darwin and has CPUTYPE arm64
- is_mac_intel - it is darwin and has CPUTYPE x86_64
- is_bsd - any BSD like OS - the CPUTYPE env is (darwin|freebsd|openbsd|netbsd)*
- is_solaris - the CPUTYPE env is solaris*
- is_cygwin - the CPUTYPE env is cygwin*
- is_msys - the CPUTYPE env is msys*
- is_windows - the CPUTYPE env is (cygwin|msys)*
