Christopher Ferris 4568f4bc0f Verify that the elf matches the expected arch.
To avoid a case where a malicious app might try and trick the system to
create an elf and register object that mismatches, always verify that they
are the same arch.

Test: Ran unit tests.

Christopher Ferris e8c4ecf49e Always init gnu_debugdata interface if it exists.
Every real call always sets the value to true to init the gnu_debugdata
interface, so remove this parameter.

Test: Builds, unit tests pass.

Christopher Ferris 9d5712c123 Implement support for linker rosegment option.
The rosegment linker option results in two maps containing the elf data
existing. One is an execute map where the code lives, and the other is the
read-only segment which contains the elf header information. If the file
backing a shared library in memory is not readable, then the new code
will attempt to find the read-only map that has the same name as the
current execute segment, and that is at offest zero in the file.

Add new unit tests for this functionality.

Add the missing MapInfoCreateMemoryTest.cpp to the list of tests.

Bug: 109657296

Test: Pass new unit tests.
Test: All unit libbacktrace/libunwindstack tests pass with rosegment enabled.
