Fixes to hardware config editing/display

[mikee47]

If name not specified when loading config then 'save' raises exception

For example, Basic_Ota sample doesn't have its name field set in ota.hw:

• Run make hwconfig-edit
• Click 'save'

So ensure we provide a default name based on filename.

Ensure all sample .hw files have names

For consistency.

Remove 'unused_before' and 'unused_after' fields from make hwconfig output

These are only used for map building so shouldn't be visible.
Example:

        "phy_init": {
            "device": "spiFlash",
            "address": "0x000fc000",
            "size": "4K",
            "type": "data",
            "subtype": "phy",
            "readonly": false,
            "encrypted": false,
            "filename": "$(FLASH_INIT_DATA)",
            "unused_before": 0, ///<
            "unused_after": 0   ///< Don't show
        },

Don't set name, comment fields from option data

For example, Basic_Blink sample uses default config. Running make hwconfig gives:

{
    "name": "Standard config with single ROM",
    "comment": "Should work with any Esp8266 variant",
    "arch": "Esp8266",
    "options": [],

If we run make hwconfig HWCONFIG_OPTS=4m we get this:

{
    "name": "",
    "comment": "",
    "arch": "Esp8266",
    "options": [
        "4m"
    ],

The name and comment have been wiped out, should be as before.

Fix use of not in and is not operators

e.g. x not in [...] preferred to not x in [...]

PR Summary

• Introduced a New Function to Extract File Name
  A new function named get_basename_no_ext has been created in the hwconfig/common.py file. It is designed to extract the base name of a file without its extension.

• Enhanced Config Class with Additional Attributes
  The Config class in the hwconfig/config.py file has two new attributes, name and comment, making it more detailed and robust.

• Modifications to Key Functions for Better Performance
  The functions get_dict_value, loadConfig, and the dict function in hwconfig/editor.py and hwconfig/partition.py respectively have been updated to improve their output and enhance their performance.

• New Function to Save Files
  A new file saving function, fileSave, has been created in the hwconfig/editor.py file. It is designed to streamline the saving process of various documents.

• Updated Hardware Configuration Files
  Several hardware configuration files, namely basic_ifs_Esp32.hw, basic_ifs_Esp8266.hw, basic_ifs_Host.hw, basic_ifs_Rp2040.hw, ota.hw, ftpserver-esp32.hw, and ftpserver-esp8266.hw have been updated to reflect the latest changes and improvements.
