[build] Expose build timestamp, build name, and product names
Expose the build timestamp (measured in seconds since the Epoch) and
the build name (e.g. "rtl8139.rom" or "ipxe.efi"), and provide the
product name and product short name in a single centralised location.

Exploit the redefinition of iPXE error codes to include a "platform
error code" to allow for meaningful conversion of EFI_STATUS values to
iPXE errors and vice versa.

[efi] Delegate to child device's EFI_COMPONENT_NAME2_PROTOCOL, if present
EFI's device naming model requires drivers to provide names for child
devices. Allow the driver's GetControllerName() method to delegate to
an instance of EFI_COMPONENT_NAME2_PROTOCOL installed on the child
device itself (if present); this allows the SNP device to expose its
own device name via the PCI driver's GetControllerName() method.

EFI performs its own PCI bus enumeration. Respect this, and start
controlling devices only when instructed to do so by EFI.
As a side benefit, we should now correctly create multiple SNP
instances for multi-port devices.
This should also fix the problem of failing to enumerate devices
because the PCI bridges have not yet been enabled at the time the iPXE
driver is loaded.
