  [OffloadBundler] Rework the ctor of `OffloadTargetInfo` to support generic target

The current parsing of target string assumes to be in a form of
`kind-triple-targetid:feature`, such as
`hipv4-amdgcn-amd-amdhsa-gfx1030:+xnack`. Specifically, the target id does not
contain any `-`, which is not the case for generic target. Also, a generic
target may contain one or more `-`, such as `gfx10-3-generic` and
`gfx12-generic`. As a result, we can no longer depend on `rstrip` to get things
work right. This patch reworks the logic to parse the target string to make it
more robust, as well as supporting generic target.
