[PATCH v1 14/22] DynamicTablesPkg: Dynamic Table Manager Dxe

[Sami Mujawar <sami.mujawar@arm.com>]

The dynamic table manager implements the top level component
that drives the table generation and installation process.
It uses the configuration manager protocol to get the list
of tables to be installed from the configuration manager.
It iterates through the list of tables, requests the table
factories for corresponding generators and invokes the
generator interface to build the tables.

+/** Entrypoint of Dynamic Table Manager Dxe.
+
+  The Dynamic Table Manager uses the Configuration Manager Protocol
+  to get the list of ACPI and SMBIOS tables to install. For each table
+  in the list it requests the corresponding ACPI/SMBIOS table factory for
+  a generator capable of building the ACPI/SMBIOS table.
+  If a suitable table generator is found, it invokes the generator interface
+  to build the table. The Dynamic Table Manager then installs the
+  table and invokes another generator interface to free any resources
+  allocated for building the table.
+
+  @param  ImageHandle

+
+  @retval EFI_SUCCESS           Success.
+  @retval EFI_OUT_OF_RESOURCES  Memory allocation failed.
