internal/lsp/source/genapijson: add 'gopls_' prefix to commands

This CL adjusts the genapijson program as the follow up of the command
name change cls. The program loads the command list by parsing the
source code and uses the result to compute the codelens list.
Involved data types are also used for JSON marshalling, so I just
update the command name after codelens list loading is done using
the command data.

Updates golang/go#41187
Fixes golang/go#41985
