Add bash tab completions

[mattytrentini]

Adding bash tab completions would be immensely helpful.

build/clean

>mpbuild build nuc[tab][tab] should list all Nucleo boards. >mpbuild build nucleo_f0[tab] should complete (with NUCLEO_F091RC).

Consider adding optional port syntax:

>mpbuild build rp2/n[tab] should complete with NULLBITS_BIT_C_PRO, ie ignoring all of the Nucleo boards.

list

Should probably make the port an optional argument and then the following could be supported:

>mpbuild list s[tab][tab] would list stm32 samd, >mpbuild list sa[tab] would complete with samd. The output would then be filtered to that port.

Experiments with this feature is coming along nicely now. After re-learning how bash completion scripts work, I discovered that typer has a feature to perform CLI Option autocompletion. It supports everything I wish to do and apparently works on bash/zsh/powershell/fish.

It was pretty easy to implement board, variant and port support - and typer does subcommand and switch autocomplete for free!

So, these currently work:

>mpbuild b<tab>uild
>mpbuild build PYB<tab><tab>
PYBD_SF2    PYBD_SF3    PYBD_SF6    PYBLITEV10  PYBV10      PYBV11
> mpbuild build PYBL<tab>ITEV10
> mpbuild build PYBLITEV10 <tab><tab>
DP         DP_THREAD  NETWORK    THREAD
> mpbuild build PYBLITEV10 DP_<tab>THREAD
> mpbuild build PYBLITEV10 DP_THREAD<enter>

>mpbuild list s<tab><tab>
samd   stm32
>mpbuild list st<tab>m32

It still needs a little polish but I'll push it up soon.

I'm satisfied with the solution in #39.

I haven't added the 'optional port syntax' but that can come later.
