SyntaxWarning from gen_compile_commands.py

[LuminousXLB]

I see there's noqa: W605 to suppress the complaint "Invalid escape sequence" from linter, but this is becoming a SyntaxWarning from Python 3.12 (ref).

optee_os/scripts/gen_compile_commands.py

Lines 176 to 180 in 956c2d5

	# The .cmd files are intended to be included directly by Make, so they
	# escape the pound sign '#', either as '\#' or '$(pound)' (depending on the
	# kernel version). The compile_commands.json file is not interpreted
	# by Make, so this code replaces the escaped version with '#'.
	prefix = command_prefix.replace('\#', '#').replace('$(pound)', '#') # noqa: W605

I'd propose we properly escape the back slash by changing it to

command_prefix.replace(r'\#', '#')

Hi @LuminousXLB, your are probably right. Would you mind creating a pull request?

Yes @jforissier , I've opened a PR on this.
