Documentation,cmd/dlv: clean up command line usage help (#3395) 
Due to some very old mistakes too many of Delve's flags are declared as
persistent on cobra's root command. For example the headless flag is a
global flag but does not apply to connect, dap or trace; the backend
flag does not apply to replay, core and dap; etc.

Almost all global flags should have been declared as local flags on
individual subcommands. Unfortunately we can not change this without
breaking backwards compatibility, for example:

   dlv --headless debug

would not parse if headless was a flag of debug instead of a global
flag.

Instead we alter usage function and the markdown generation script to
strategically hide the flags that don't apply.

Fixes #2361

dlv core

Examine a core dump.

Synopsis

Examine a core dump (only supports linux and windows core dumps).

The core command will open the specified core file and the associated executable and let you examine the state of the process when the core dump was taken.

Currently supports linux/amd64 and linux/arm64 core files, windows/amd64 minidumps and core files generated by Delve's 'dump' command.

dlv core <executable> <core> [flags]

Options

  -h, --help   help for core
