This patch includes ME specification datastructures for various ME
versions. Including the ME specification in common code will help

not necessarily share the same SoC directory.

Introduce at new config option CONFIG_FSP_PUBLISH_MBP_HOB to control
the creation of ME_BIOS_PAYLOAD_HOB (MBP HOB) by FSP.
This new option is hooked with `SkipMbpHob` UPD and is always disabled
for RPL & ADL-N based ChromeOS platforms.
It is not disabled for ADL-P based platforms because ADL-P FSP relies
on MBP HOB for ChipsetInit version for ChipsetInit sync. As ChipsetInit
sync doesn't occur if no MBP HOB, so it results S0ix issue. This
limitation is addressed in the later platforms so creation of MBP HOB
can be skipped for ADL-N and RPL based platforms.
This made skip_mbp_hob SOC chip config variable redundant which is also
removed as part of this change.

VGA defineds the extended ASCII set based on CP437, but there is a bug
on printing them: in vga_write_at_offset(), we perform a bitwise or
between 'unsigned short' and 'signed char':
```
p[i] = 0x0F00 | string[i];
```
If we want to show an extended ASCII character, string[i] will be
negative and this bitwise operation will fail due to their implicit
casting rule: convert signed char to unsigned short by adding 65536.
To fix this, we need to cast the string to unsigned char manually
somewhere. Since we still want to leverage the built-in string utilities
which only accepts const char*, we still preserve the original
prototypes before, and cast it until we write into the frame buffer.

The EFS entry at offset 0x14 can point to either the first level PSP
directory table or to the PSP combo directory structure that was used
before the introduction of the AMD A/B recovery scheme. This scheme is
not to be confused with the VBOOT scheme. The PSP verstage code checks
if the header this entry points to begins with the PSP_COOKIE, which
indicates the entry is a first level PSP directory table. Due to that,
the EFS entry at offset 0x14 is always expected to point to a PSP
directory table, so rename combo_psp_directory to new_psp_directory to
match the actual usage. This EFS entry that points to the PSP directory
table is called new_psp_directory, since the entry at EFS offset 0x10
was used on some early AMD chips to point to the older PSP directory
table and that one is already called psp_directory. amdfwtool uses the
same naming scheme for those two PSP directory table pointers.

The ctags tool (called by ctags-project target) currently complains
about not finding certain files.
The project_filelist.txt generation includes the compiler
generated "*.d" files, except for files found in build/util. Most file
paths in these "*.d" files are file paths relative to the root
directory of coreboot. Some projects though are compiled separately from
coreboot (e.g. payload, vboot, util). Some of these (e.g. util, vboot)
are also put into the build directory of coreboot and relative file
paths are relative to these projects instead of coreboot. This has the
uncanning side effect that the ctags Makefile target can't find these
files, since they are not relative to the coreboot root directory.
This patch also excludes the build/external directory from those files,
since they contain 'separately' compiled projects like 3rdparty/vboot.
That fixes the ctags-project Makefile target.
