DynamicTablesPkg: Update ASL build options

The EdkII BaseTools have been updated to facilitate the
generation of C file containing AML data using the AmlToC
script. The build system follows the following sequence
for an ASL file compilation:
 - The ASL file is preprocessed using the C preprocessor
 - The Trim utility prunes the preprocessed file to removed
   unwanted data.
 - This file is compiled using an ASL compiler to generate
   an AML file.
 - The AmlToC python script reads the AML data and generates
   a C file with an array containing the AML data.
 - This C file containing a unique symbol name for the AML
   data array is then compiled with the firmware module.

This removes the dependency on the ACPICA iASL compiler's
"-tc" option which achieved the same effect but was less
portable. Therefore, remove the "-tc" option from the ASL
flags as this option is only been supported by the ACPICA
iASL compiler.
