[lldb][Bazel] Add DynamicLoaderAcceleratorGDBRemote to Bazel overlay (#240539)
Commit e445a066c870 (#217393) added DynamicLoaderAcceleratorGDBRemote to
the CMake build, but did not register it in the Bazel overlay. As a
result, LLDB built with Bazel does not link or initialize the
accelerator-gdb-remote dynamic loader plugin, causing
TestAcceleratorDynamicLoader to fail.
Add PluginDynamicLoaderAcceleratorGDBRemote (including //lldb:Headers
for layering_check and matching the CMake LINK_LIBS) and register
DynamicLoaderAcceleratorGDBRemote in DEFAULT_PLUGINS.
