  [offload-arch] Report gfx1250-strict to match rocminfo (#224480)

## Motivation

offload-arch would print gfx1250, but rocminfo reports gfx1250-strict on
revision 0s. We want to print the gfx1250-strict too.

Note: This is based off a [similar PR in
rocm-systems](https://github.com/ROCm/rocm-systems/pull/11639).

## Required Changes

* llvm already can parse the gfx1250 -strict target, so no changes
necessary there.
* offload-arch already printed gfx1250, so just needed to get the ASIC
Revision, which is in bits 25:22 in the capability property.
* If ASIC Revision is 0 and gfx_target_version is gfx1250, then report
"gfx1250-strict"

## Testing

* Tested this on a gfx1250-strict and offload-arch reports correctly.
* Added two unit tests to check for "gfx1250" v "gfx1250-strict"
depending on ASIC revision and guard against accidental parsing of
"capability2"
