Replace fragile cursor compensation with full-line redraws where needed,
fix Ctrl+W buffer/screen corruption, properly consume unrecognized CSI
sequences, and always clean up leaked local-echo characters from buggy
serial drivers. These changes make line editing consistent across
terminals while preserving existing behavior.

readline cached the current prompt only when TAB completion was enabled,
even though line-editing redraws also depend on that cached prompt.
With TAB completion disabled, full-line redraws erased the prompt and
repainted only the command buffer. Make the prompt cache available
whenever line editing is enabled.

The original readline_common.c file had some duplicated code that was
causing the nsh to be more than 1KB bigger. This clean up will allow
adding line editing without increasing the final firmware size too much.

This commit adds support to nsh> command line editing. This is one
of the most missing feature of the NuttShell. If you typed a long
command line and make a mistake you need to press Backspace and
remove everything until reach that typo. Only the basic editing
feature is enabled by default (left/right keys movement, Home/End
to move to the beginning or ending of the command line).
More advanced features are available when CONFIG_READLINE_EDIT_EMACS
is selected. It enables the Emacs-style control keys (Ctrl+A/B/D/E/F/K/U/W)
that allow more flexible line editing.
Other more advanced feature is enabled when CONFIG_READLINE_CMD_HISTORY
and CONFIG_READLINE_EDIT_EMACS_REVERSE_SEARCH are enabled. It allows the
user to press Ctrl+R to do reverse search in the command line history.

There is a POSIX defined interface to get file descriptor from file_struct
stream. Applications should use it and not access the structure directly.

Let's echo character by serial driver,
this will imporve the experience of telnetd,
which will display input command and newline twice.
And also enhance the compatiblity with some third party
linux readline based application (like WAMR repl).
