Support for static Boost builds

**Describe the issue**

Using a static build of Boost results in a linker error like the one seen below in the build log. The root cause is the build system setting [BOOST_ALL_DYN_LINK](https://github.com/Autodesk/maya-usd/blob/c95fcf2c82b8dac659b09bcdd2898e6fab2484f2/cmake/compiler_config.cmake#L46) which forces Boost to use the dynamic symbol names.

**Additional context**

To work around, you can just delete the define.

Start in cmake/compiler_config.cmake at the BOOST_ALL_DYN_LINK setting and review how the build config handles static versus dynamic Boost libraries. Reproduce the Windows static Boost build from the reported log, then verify that the mayaUsd link completes without the unresolved Boost symbols.
