chore(xcelium): remove the -enable_cmdline_define_redefinition argument

[tymonx]

Closes #532

This is not needed because every group of files is compiled by using the -makelib <library> <options>... <file> -endlib that is creating own scope where options like -define NAME=VALUE are not interleaving with each other.

Each groups of files is created based on files, library name and defines:

edalize/edalize/tools/xcelium.py

Lines 150 to 164 in e8feae4

	for fg in filegroups:
	# Ignore empty file groups
	if fg[1]:
	(file_type, lib, defines) = fg[0]
	if lib:
	files_cmd += ["-makelib", lib]
	for k, v in defines.items():
	files_cmd += ["-define", f"{k}={v}"]
	if file_type.startswith("systemVerilogSource"):
	files_cmd += ["-sv"]
	if file_type in self.FILE_TYPE_TO_FEATURE_FLAG:
	files_cmd += [self.FILE_TYPE_TO_FEATURE_FLAG[file_type]]
	files_cmd += fg[1]
	if lib:
	files_cmd += ["-endlib"]

Additionally, the lib is always present and it is not empty:

edalize/edalize/tools/xcelium.py

Line 140 in e8feae4

lib = f.get("logical_name", "worklib")

In case of the Xcelium simulator, if user doesn't provide the library name explicitly, everything is compiled under the default library worklib.

So this:

xrun -enable_cmdline_define_redefinition argument -define KEY=VALUE1 <file1> -define KEY=VALUE2  <file2> ...

Could be replaced with explicitly -makelib worklib <options> <file> -endlib:

xrun -makelib worklib -define KEY=VALUE1 <file1> -endlib -makelib worklib -define KEY=VALUE2 <file2> -endlib ...

And the -enable_cmdline_define_redefinition argument is not needed. That argument is not documented, not present in the xrun -helpall and it is not supported by the Cadence Xcelium below version 25.
