microbnechmark so that it can retrieve measurements and generate reports for zygotes and trustlets independently Precisely, it performs the following: - convert some `info` prints to `debug` to not affect the measurements - set the `AllocationRange` of the `Manifest`, `Libos` and `PAL` correctly - add an `AllocationRange` in the base context for the `function` - `AllocationRange`s in the base context now hold their actual size instead of the amount of pages they span to have accurate, correct measurements - make `addr_to_idx` a public function as it is needed for identifying the mapped regions in the attestation report generation microbenchmark - add a `TP_FUNCTION_START_VADDR` global variable for the predefined virtual address of the function mapping - set the `features.set_restrict_injection` to `false` in the `igvmbuilder` to get correct and comparable measurements in the CVM reports - add helper functions and helper options in the `attest` call in `attestation/monitor.rs` for getting the measurements independently Signed-off-by: dimstav23 <[email protected]>

Attestation microbenchmark
This PR introduces the attestation report generation microbenchmark.
