Given vectors $\overrightarrow{a}=(\cos \omega x-\sin \omega x,\sin \omega x)$ and $\overrightarrow{b}=(-\cos \omega x-\sin \omega x,2\sqrt{3}\cos \omega x)$, where $\omega$ and $\lambda$ are constants, and $\omega \in (\frac{1}{2}, 1)$. The graph of the function $f(x)=\overrightarrow{a}\cdot \overrightarrow{b}+\lambda$ is symmetric about the line $x=\pi$. Find:<br/>
$(1)$ The smallest positive period of the function $f(x)$;<br/>
$(2)$ If the graph of $y=f(x)$ passes through the point $(\frac{\pi}{4},0)$, find the range of values of the function $f(x)$ on the interval $[0,\frac{3\pi}{5}]$.
