gfx12xx (RDNA4) regex update

[wiersema1]

Summary

Updated regex in Tools/Cmake/AMReXSetDefines.cmake to catch gfx12xx devices and use the correct wavefront size.

Additional background

My build environment includes

• ROCm 6.2.4 / HIP 6.2.41134 / AMD Clang 18.0.0
• GCC 13.3.0 (Ubuntu 24.04)
• CMake 3.28.3

Checklist

The proposed changes:

• fix a bug or incorrect behavior in AMReX
• add new capabilities to AMReX
• changes answers in the test suite to more than roundoff level
• are likely to significantly affect the results of downstream AMReX users
• include documentation in the code and/or rst files, if appropriate

Suggested change

	if (${AMReX_AMD_ARCH} MATCHES "gfx1[012].*")
	if (${AMReX_AMD_ARCH} MATCHES "gfx1???")

Could you tell me if this works?
