[Feature Request] Adding the option to increase partition size for x86 builds

[molink36]

Currently, there is a 100MB partition limit set in OpenWRT firmware-selector for x86 builds. This limitation makes it impossible to create firmware with pre-installed packages exceeding 100MB. Setting an option to change build partition size or setting the default partition size to a larger size, for example 1GB, would be great.

If you do a PR on this, make sure to include a warning that when installing an image with a different rootfs partition size than the one on the device, that sysupgrade's backup/restore doesn't work.

I warn owut users about it here: https://openwrt.org/docs/guide-user/installation/sysupgrade.owut#expanding_root_file_system

If this is added to FS, then I'd think a similar warning would be appropriate.

This might be too much of a niche use case. The firmware selector / ASU is not meant to cover all use cases (as I understand it).

I agree, too much can go wrong in the FS setting (if you forget to set it or set it wrong, then you lose your config, that sort of thing). That's why I've been subtly resistant to adding it to FS, while fully supporting it in owut and partially supporting it in LuCI ASU app... ("Partial" in LuCI means the app respects the setting, but offers no GUI access to it. This -I hope- forces users into reading the docs and understanding the risks and pitfalls.)

Dear @efahl @mwarning

Unfortunately, I am not a programmer, so I cannot contribute to this great project by doing a pull request.
I have created a list of packages that I need, and whenever I want to install OpenWRT on an x64 computer, I create a custom firmware image that includes the mentioned package list. Recently, the package size has exceeded the 100MB limit (to be precise, 250MB).
Considering the fact that real use case scenarios for an x64 computer usually requires a partition size larger than the default 100MB, I believe that this default value should be increased, or at least the option to be able to change it should be made available.
