composer@2.x-hal is a header library. Any of the shared libraries it depends on must also be included by anyone who includes composer@2.x-hal. This means when we add a new version of mapper, anyone who uses composer@2.x-hal must also include the new version of the mapper. Vendors that depend on composer@2.x-hal are broken every time we add a new mapper. This patch refactors ComposerResources into a seperate shared library. ComposerResources contains all of the mapper code. composer@2.x-hal will depend on the new composer@2.x-resource hal. Everyone downstream must also add the composer@2.x-resource file now. However, they will not be broken again when we add a new mapper version. Bug: 136016160 Test: Compiles and boots Change-Id: I208a954a941ed65938074cd3efb8a6893a2bc1eb
