Change the smbios structure to use a 4 byte u32 signature field
instead of a 4 byte character string field. In practice, this allows
the compiler to place the signature in the initialize code segment and
thus makes it less likely the signature would be found in the
f-segment. (If the smbios signature is found in the f-segment it can
confuse some table scans.)

Check fw_cfg for the presence of an aggregate set of smbios
tables (etc/smbios/smbios-tables) and an entry point structure
(etc/smbios/smbios-anchor), and, if found, use them instead of
generating entries locally.
We ensure the presence of a type 0 (bios information) structure
by generating it locally if necessary, which is expected to be
the common case.

Add a note to the code that generates the pir, mptable, smbios, and
smbios tables that no new changes are expected. Going forward, it is
expected that if any changes are needed to these bios tables that
SeaBIOS will get the tables passed in from upstream.

Use the biostables.c copy_pir(), copy_smbios(), copy_acpi_rsdp(), and
copy_mptable() code even when using the legacy bios table generation
code. This unifies the final bios table deployment code between qemu,
coreboot, and csm.

After this change, src/fw/smbios.c only contains the legacy code for
generating SMBIOS tables. This change only contains code movement -
no logic is changed.

Make sure to initialize the entire smbios area to zero so that any
field not explicitly initialized does not have random values. (It was
found that the memory_error_information_handle field in smbios_type_17
was not being set.)

qemu may pass us zero-length strings for smbios fields, when starting
qemu this way ...
qemu -smbios type=1,version=,serial=test
... for example.
Today we don't specifically handle them and simply append them to the
string list. Therefore we get two string-terminating zeros in a row.
Result is that we by accident create a end-of-entry marker in the middle
of the entry.
Fix this by handling zero-length strings like non-present strings.

Also, sort the order of include files in the c files.
