Create action translator for Textfile builder to ninja

[dmoody256]

The Textfile builder could have an automatic translator to prevent needing to callback to scons, similar to the MkDir or Copy Builder:

scons/SCons/Tool/ninja/Rules.py

Lines 37 to 52 in f709352

	def _mkdir_action_function(env, node):
	return {
	"outputs": get_outputs(node),
	"rule": get_rule(node, "GENERATED_CMD"),
	# implicit explicitly omitted, we translate these so they can be
	# used by anything that depends on these but commonly this is
	# hit with a node that will depend on all of the fake
	# srcnode's that SCons will never give us a rule for leading
	# to an invalid ninja file.
	"variables": {
	# On Windows mkdir "-p" is always on
	"cmd": "mkdir {args}".format(
	args = ' '.join(get_outputs(node)) + " & exit /b 0" if env["PLATFORM"] == "win32" else "-p " + ' '.join(get_outputs(node)),
	),
	},
	}

This was requested by a user in the scon's user mailing list thread: https://pairlist4.pair.net/pipermail/scons-users/2022-May/008985.html

@dmoody256 Are there any plans to change this issue in the near future?

There's no PR and it's not scheduled for any planned release at this time.
