feat: Add support for using Product Name

[Geometrically]

This PR is based off the work here gitbutlerapp#1 by @Krivi. (most of this PR description was taken from there- it was very well written!)

Background:

This change in Tauri https://github.com/tauri-apps/tauri/pull/9375/files, which is noted as a refactor is in fact a breaking change as far as the app updater is concerned.

The impact is that because the binary now has a different name, it is not possible to smoothly update a Tauri application via the updater if the initial version of the app is using v1.x and the new version is using v2.x.

Approach:

I'm introducing here an option for the tauri-cli (tauri-bundler) for producing the same binary names it did in v1, allowing users to update the app via the updater. In order to enable this behavior, set the environment variable

V1_COMPATIBLE_BIN_NAME=true

Previously, the bundler did the rename just after building the binary. I poked and tried doing the same once again, but because quite a lot of the code in that bundler changed since that was merged, it felt possibly more error prone (since now the rest of the code can safely assume that the binary is the crate name)

So, instead, my approach is to do the rename the binary at the last moment (i.e. in the bundle_project function in eg. app.rs)

fixes #10548

I am looking into all issues related to v1 -> v2 updater so bear with me until I get this all sorted out.

No worries- I fully tested this on Windows/MacOS/Linux and everything seems to be working as expected :)

I believe we can close this one now that we have #10939 #10996 #10977 #10969 #10967 #10962 #10952

yeah, that correct, this is not longer needed and if productName needs to be used, you can set the new mainBinaryName option to the same value as productName.

Apologies for the inconvenience.
