Failed to build `ARM_MUSCA_B1` with this example

What target(s) are you using?
`ARM_MUSCA_B1`

What toolchain(s) are you using?
GCC_ARM and ARMC6

What version of Mbed OS are you using (tag or sha)?
Master or `mbed-os-6.4.0`

to reproduce:
mbed test -t ARM -m ARM_MUSCA_B1

Failed to build `ARM_MUSCA_B1` with this example
```
[Fatal Error] main.cpp@21,10: psa_initial_attestation_api.h: No such file or directory
[ERROR] ./main.cpp:21:10: fatal error: psa_initial_attestation_api.h: No such file or directory
21 | #include "psa_initial_attestation_api.h"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
```

Reproduce the failure with `mbed test -t ARM -m ARM_MUSCA_B1` and inspect `main.cpp` at line 21, where `psa_initial_attestation_api.h` is included. Trace the example's include and build configuration for GCC_ARM and ARMC6; done means the example builds successfully for `ARM_MUSCA_B1` on the stated Mbed OS versions.
