Remove Alloy Bootstrap (M128)

[amaitland]

CEF is going to remove the Alloy Bootstrap

• Upstream issue alloy: Delete Alloy bootstrap (M128) chromiumembedded/cef#3685
• Announcement

Starting in M125 it will be possible to migrate over to the Chrome Bootstrap.

[amaitland]

CefSharp will likely switch to using the Chrome Bootstrap by default in M126 to ensure any underlying issues are identified before the alloy bootstrap is removed.
