ShellPkg: Add acpiview tool to dump ACPI tables 

This program is provided to allow examination of ACPI table contents
from the UEFI Shell.  This can help with investigations, especially at
that stage where the tables are not enabling an OS to boot.
The program is not exhaustive, and only encapsulates detailed knowledge
of a limited number of table types.

Default behaviour is to display the content of all tables installed.
'Known' table types will be parsed and displayed with descriptions and
field values.  Where appropriate a degree of consistency checking is
done and errors may be reported in the output.
Other table types will be displayed as an array of Hexadecimal bytes.

To facilitate debugging, the -s and -d options can be used to generate a
binary file image of a table that can be copied elsewhere for
investigation using tools such as those provided by acpica.org.  This is
especially relevant for AML type tables like DSDT and SSDT.

The inspiration for this is the existing smbiosview Debug1 Shell
command.

Many tables are not explicitly handled, in part because no examples are
available for our testing.

The program is designed to be extended to new tables with minimal
effort, and contributions are invited.

"Display ACPI Table information.\r\n"
".SH SYNOPSIS\r\n"
" \r\n"
"ACPIVIEW [[-?] | [[-l] | [-s AcpiTable [-d]]] [-c] [-v] [-h Highlight]]\r\n"
" \r\n"
".SH OPTIONS\r\n"
" \r\n"
" -l - Display list of installed ACPI Tables.\r\n"
" -s - Display only the specified AcpiTable type.\r\n"
" AcpiTable : The required ACPI Table type.\r\n"
" -d - Generate a binary file dump of the specified AcpiTable.\r\n"
" -c - Consistency checking (enabled by default).\r\n"
" -v - Display verbose data (enabled by default).\r\n"
" -h - Enable/Disable Colour Highlighting.\r\n"
" Highlight : TRUE/ON enables highlighting;\r\n"
" FALSE/OFF (default) disables highlighting.\r\n"
" -? - Show help.\r\n"
" \r\n"
".SH DESCRIPTION\r\n"
" \r\n"
" This program is provided to allow examination of ACPI table values from the\r\n"
" UEFI Shell. This can help with investigations, especially at that stage where\r\n"
" the tables are not enabling an OS to boot.\r\n"
" The program is not exhaustive, and only encapsulates detailed knowledge of a\r\n"
" limited number of table types.\r\n"
" \r\n"
" Default behaviour is to display the content of all tables installed.\r\n"
" 'Known' table types (listed in NOTES below) will be parsed and displayed\r\n"
" with descriptions and field values. Where appropriate a degree of consistency\r\n"
" checking is done and errors may be reported in the output.\r\n"
" Other table types will be displayed as an array of Hexadecimal bytes.\r\n"
" \r\n"
" To facilitate debugging, the -s and -d options can be used to generate a\r\n"
" binary file image of a table that can be copied elsewhere for investigation\r\n"
" using tools such as those provided by acpica.org. This is especially relevant\r\n"
" for AML type tables like DSDT and SSDT.\r\n"
" \r\n"
"NOTES:\r\n"
" 1. The AcpiTable parameter can match any installed table type.\r\n"
" Tables without specific handling will be displayed as a raw hex dump (or\r\n"
" dumped to a file if -d is used).\r\n"
" 2. Formatted display and checking is provided for these signature types:\r\n"
" APIC - Multiple APIC Description Table (MADT)\r\n"
" BGRT - Boot Graphics Resource Table\r\n"
" DBG2 - Debug Port Table 2\r\n"
" FACP - Fixed ACPI Description Table (FADT)\r\n"
" GTDT - Generic Timer Description Table\r\n"
" IORT - IO Remapping Table\r\n"
" MCFG - Memory Mapped Config Space Base Address Description Table\r\n"
" RSDP - Root System Description Pointer\r\n"
" SLIT - System Locality Information Table\r\n"
" SPCR - Serial Port Console Redirection Table\r\n"
" SRAT - System Resource Affinity Table\r\n"
" XSDT - Extended System Description Table\r\n"
" \r\n"
".SH STANDARDS\r\n"
" \r\n"
" Table details correspond to those in 'Advanced Configuration and Power\r\n"
" Interface Specification' Version 6.2 Errata A, [September 2017]\r\n"
" (http://www.uefi.org/sites/default/files/resources/ACPI%206_2_A_Sept29.pdf)\r\n"
" \r\n"
" NOTE: The nature of the ACPI standard means that almost all tables in 6.1 will\r\n"
" be 'backwards compatible' with prior version of the specification in\r\n"
" terms of structure, so formatted output should be correct. The main\r\n"
" exception will be that previously 'reserved' fields will be reported\r\n"
" with new names, where they have been added in later versions of the\r\n"
" specification.\r\n"
" \r\n"
".SH EXAMPLES\r\n"
" \r\n"
" \r\n"
"EXAMPLES:\r\n"
" * To display a list of the installed table types:\r\n"
" fs0:\> acpiview -l\r\n"
" \r\n"
" * To parse and display a specific table type:\r\n"
" fs0:\> acpiview -s GTDT\r\n"
" \r\n"
" * To save a binary dump of the contents of a table to a file\r\n"
" in the current working directory:\r\n"
" fs0:\> acpiview -s DSDT -d\r\n"
" \r\n"
" * To display contents of all ACPI tables:\r\n"
" fs0:\> acpiview\r\n"
" \r\n"
".SH RETURNVALUES\r\n"
" \r\n"
"RETURN VALUES:\r\n"
" SHELL_SUCCESS Data was displayed as requested.\r\n"
" SHELL_INVALID_PARAMETER ACPI Table parsing failed.\r\n"
