cmake: accept glslang's current tool name and document Python 3 (#1161)

* cmake: accept glslang's current tool name and document Python 3

Official glslang release archives for Windows ship the compiler only as
glslang.exe, so configuring with one of them on PATH could not find
glslangValidator. Fall back to glslang; glslangValidator is still
preferred where both exist.

The bundled SPIRV-Tools needs Python 3 at configure time, which the
Windows build requirements did not mention.

* docs: list Python 3 in the Linux and macOS prerequisites

The bundled SPIRV-Tools calls find_host_package(Python3 REQUIRED) on every platform, so the apt and Homebrew package lists need it too, not only the Windows requirements.

* cmake: remove glslang naming comment
