cr50: use LTO module for TPM2
In order to reduce code footprint, do not link TPM2 library modules,
instead build TPM2 as a single relocatable object module, a collection
of library sources compiled and linked with LTO enabled.
BUG=b:65253310
TEST=observed code space reduced by 1428 bytes, the bss_libtpm2
section remained practically unchanged:
before:
*** 5548 bytes in flash and 5652 bytes in RAM still ...
000104d0 B __bss_libtpm2_start
000155d7 B __bss_libtpm2_end
after:
*** 6976 bytes in flash and 5652 bytes in RAM still ...
000104d0 B __bss_libtpm2_start
000155d4 B __bss_libtpm2_end
Verified that the new Cr50 image allows a Chrome OS to successfully
boot and restart.
