[feature] Added silent parameter to the dap.repl.execute function to not repeat the command after execution.

[banana59]

Example for Python

local repl = require('dap.repl')

repl.commands = vim.tbl_extend('force', repl.commands, {
    custom_commands = {
        ["."] = function(expr)
            if not expr or expr:match("^%s*$") then
                repl.append('Usage: . <expression>')
                return
            end

            local wrapped = 'repr(' .. expr .. ')'
            repl.execute(wrapped, {context='repl', silent=true})
        end,
    }
})

Execution in the repl:

. <variable>

to show a variable without meta information.

I have tested this in python for the nvim-dap commit 6782b09.

This is related to these issues:

• Control the output verbosity or how expressions are printed in DAP REPL #737
• More variable formatting options and/or extension points  #1062

Isn't this a bit confusing if there's no separation/variable indication in the output?

Certainly in some cases, that's why the default is still verbose. I quite liked the neatness in this usecase, that . dataFrame directly outputs the content instead of first outputting the interpreted version like repr(dataFrame).

I have adjusted the implementation such that now simply entering the variable within the configuration below allows to suppress unwanted metainfo / tree output in repl.

dap.defaults.fallback.repl_hide_tree_filetypes = {
    python = true,
    python3 = true,
}

One could still use the DAP Scopes to inspect variables in more detail or for e.g. python one could use dir(<variable>).

@mfussenegger Could you please review this PR again?
