[Bug]: ACUs that are building do not fire TML when ordered to

[lL1l1]

Describe the Bug

This code disables the weapons and doesn't react on time to engine signals that the weapon should be enabled, so when the engine stops the unit from building and then checks if it has any TML to fire, it doesn't because they're disabled.

Lines 201 to 219 in fc8037d

	---@param self ACUUnit
	---@param unitBeingBuilt Unit
	---@param order string
	OnStartBuild = function(self, unitBeingBuilt, order)
	CommandUnit.OnStartBuild(self, unitBeingBuilt, order)
	-- Disable any active upgrade weapons
	local fork = false
	for label, enabled in self.WeaponEnabled do
	if enabled then
	self:SetWeaponEnabledByLabel(label, false, true)
	fork = true
	end
	end
	if fork then
	self:ForkThread(self.BuildDisable)
	end
	end,

Lines 172 to 184 in fc8037d

	---@param self ACUUnit
	BuildDisable = function(self)
	while self:IsUnitState('Building') or self:IsUnitState('Enhancing') or self:IsUnitState('Upgrading') or
	self:IsUnitState('Repairing') or self:IsUnitState('Reclaiming') do
	WaitSeconds(0.5)
	end
	for label, enabled in self.WeaponEnabled do
	if enabled then
	self:SetWeaponEnabledByLabel(label, true, true)
	end
	end
	end,

Reproduce the bug

Upgrade an ACU with TML, load it, and start building a structure. Then give a TML fire command without shift while the unit is building and it won't fire.

As a counterexample, TML SACU works correctly and does fire after issuing a fire command without shift.

   CreateUnitAtMouse('uel0001', 0,   -0.85,    1.97, -2.18294)
   CreateUnitAtMouse('xab1401', 0,   -0.46,   -5.11, -0.00000)
   CreateUnitAtMouse('xsl0301_missile', 0,    1.31,    3.14,  0.60447)

No response

Additional context

The code originates from a fix related to auto OC firing while the ACU is reclaiming/building/etc: d8d35c7
So those things have to tested in the new fix.
