libpayload: Add x86_64 (64-bit) support
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 |
+----------------+--------------------+----------------------------+
