targets: minimal uefi target support (#5452)

* runtime: split baremetal memory setup * runtime: extract Windows PE globals scan helper * compileopts,builder: add target linker flavor override * machine,runtime,targets: add minimal uefi-amd64 target * runtime,examples: add clean UEFI exit path test * machine,x86: fix amd64 ABI stack handling * machine/uefi: add CHAR16 conversion helpers * machine/uefi: add loaded image protocol support * runtime: add UEFI PE globals support * machine,runtime,x86: add UEFI time and text output support * machine,runtime,x86: add UEFI text and time support * machine,runtime,examples: add UEFI text input support * machine,examples: add UEFI graphics output support * add rest of STOP methods (direct UEFI ABI only) * runtime: fix UEFI sleep tick conversion * machine/uefi: make text input waits cooperative * address TestClangAttributes/uefi-amd64 failure * address TestConfigLinkerFlavor bug * uefi: move raw bindings to device package * strip down implementation to bare minimum * amd64: rename x86 package * do git restore upstream/dev for src/net * add smoketest for uefi-amd64; add required zeroSizeAllocPtr constant * address PR issues: remove unused files; make putchar() insert '\r' before '\n' * swap lines around
