add custom terminal executable settings

[brianignacio5]

Description

Add idf.customTerminalExecutable and idf.customTerminalExecutableArgs to customize the shell executable and shell arguments used in the extension tasks. By default it will use the vscode configured terminal.

Added them also to ESP-IDF: Doctor command output.

Shell arguments are also required as specified in VSCODE API for ShellExecutionOptions :

• The arguments to be passed to the shell executable used to run the task. Most shells
  * require special arguments to execute a command. For example bash requires the -c
  * argument to execute a command, PowerShell requires -Command and cmd requires both
  * /d and /c.

Fixes #935

Type of change

• New feature (non-breaking change which adds functionality)
