I’m considering a Canon EOS 700D with a Tamron SP 70-200mm f/2.8 and want to know whether the camera can perform autofocus micro adjustment for front- or back-focus issues. Is AF micro adjustment available on the 700D, or only on higher-end Canon bodies?

First off, Canon Auto Focus Micro Adjustment (AFMA) is based in the camera, not the lens. When a particular camera/lens combination is calibrated using AFMA, it is the camera that is adjusted. You have the option of telling the camera to use an adjustment for all lenses, or to use an adjustment only for the particular lens attached at the time you adjust it. But in either case, it is the camera that is set to act differently, not the lens.
Any AFMA adjustments made with the lens connected to one body will not carry over if that same lens is used on a different body. Depending on the exact camera model, the camera body may or may not be able to differentiate between two different copies of the same model lens. The older and lower tiered bodies that can do AFMA can not. The upper tier and other newer models can store different settings for multiple copies of the same lens model based on the lens' internal serial number.
In the case of the Canon EOS 700D/Digital Rebel T5i there is no user accessible AFMA capability. The camera can be adjusted at a Canon factory service center. In general only models with one (and sometimes two) digits have user accessible AFMA. The 50D and 70D have it but the 60D and the 40D and older models do not. (Exceptions: The 1D Mark II and 1Ds Mark II did not have it, but all 1-series bodies released since those two include it. The original 5D did not include the feature, but subsequent 5-series bodies have it.) None of the xx0D/Rebel and xx00D/Rebel series bodies include the feature.
Whether a particular lens needs it or not depends on exactly where within the manufacturing tolerances both the camera and the lens fall. Let's say the tolerance from the factory is anywhere between +5 and -5. Although the camera's design specification is "0", a little bit in either direction is deemed by the maker to be acceptable and within tolerances. If the camera is a little off in a -4 direction and the lens is a little off in a +4 direction, than they cancel each other out perfectly and would perform well together. On the other hand, if both the camera and lens are off in the same direction and the error is compounded, then an adjustment is needed. If the camera doesn't offer user accessible AFMA, then a trip to a factory service center for both the camera and lens would be needed. To adjust the camera requires the lens to be attached as well. If your camera performs fine with your other lenses you should request that only the lens be adjusted to match your camera.

No. The Canon EOS 700D does not support autofocus micro adjustment (AFMA).
AF micro adjustment is a camera-body feature, not a lens feature. When available, the adjustment is stored in the camera and applied to that camera/lens combination. It does not transfer with the lens to another body.
On Canon bodies, AFMA has generally been limited to higher-end models. The Rebel series, including the 700D, does not include it. If you need in-camera AF fine-tuning for a lens/body mismatch, you would need a compatible higher-end Canon body instead.
