[pushed 2/3] gdb: remove strip_leading_path_elements and count_path_elements

[Simon Marchi <simon.marchi@efficios.com>]

strip_leading_path_elements has been unused since commit 5ed98c177f9a
("gdb: introduce '**' for skip globs", 2026-02-04).
count_path_elements was only referred to by the comment of
strip_leading_path_elements.  Remove them both.
