This patch introduces x86_64 (64-bit) support to the payload, building
upon the existing x86 (32-bit) architecture. Files necessary for 64-bit
compilation are now guarded by the `CONFIG_LP_ARCH_X86_64` Kconfig
option.
BUG=b:242829490
TEST=Able to verify all valid combinations between coreboot and
payload with this patch.
Payload Entry Point Behavior with below code.
+----------------+--------------------+----------------------------+
| LP_ARCH_X86_64 | Payload Entry Mode | Description |
+----------------+--------------------+----------------------------+
| No | 32-bit | Direct protected mode init |
+----------------+--------------------+----------------------------+
| Yes | 32-bit | Protected to long mode |
+----------------+--------------------+----------------------------+
| Yes | 64-bit | Long mode initialization |

This patch moves commonlib/stdlib.h -> commonlib/bsd/stdlib.h, since
all code is BSD licensed anyway.
It also moves some code from libpayloads stdlib.h to
commonlib/bsd/stdlib.h so that it can be shared with coreboot. This is
useful for a subsequent commit that adds devicetree.c into commonlib.
Also we don't support DMA on arm platforms in coreboot (only libpayload)
therefore `dma_malloc()` has been removed and `dma_coherent()` has been
moved to architecture specific functions. Any architecture that tries to
use `dma_coherent()` now will get a compile time error. In order to not
break current platforms like mb/google/herobrine which make use of the
commonlib/storage/sdhci.c controller which in turn uses `dma_coherent` a
stub has been added to arch/arm64/dma.c.

The .inc suffix is confusing to various tools as it's not specific to
Makefiles. This means that editors don't recognize the files, and don't
open them with highlighting and any other specific editor functionality.
This issue is also seen in the release notes generation script where
Makefiles get renamed before running cloc.
