This change defers creating Support/Caching.cpp's cache directory until
it actually writes to the cache.
This allows using Caching library in a read-only fashion. If read-only,
the cache is guaranteed not to write to disk. This keeps tools using
DebugInfod (currently llvm-symbolizer) hermetic when not configured to
perform remote lookups.

The directory returned from `cache_directory` may not be writable if the unit tests are run with limited permissions (e.g. if $HOME is not writable).
This fixes a unit test of the debuginfod client to set the cache path to the system temporary directory to avoid this issue.

Following the discussion in D112753, this moves the HTTPClient from Support to Debuginfod library so that tools depending on Support do not automatically depend on Curl as well. This also removes `HTTPClient::initialize()` and `HTTPClient::cleanup()` from `InitLLVM` so these steps should be implemented by user tools instead.

This adds a Debuginfod client library which queries servers specified by the `DEBUGINFOD_URLS` environment variable for the debuginfo, executable, or a specified source file associated with a given build id.
