ldelf: enable ubsan support

Ubsan support was previously limited to core code. This commit moves the
ubsan runtime implementation to libutils, making it available for ldelf
and trusted applications.

As a result, ldelf will now be built with ubsan support when
CFG_CORE_SANITIZE_UNDEFINED is enabled.

Additionally, to avoid potential infinite recursion, ubsan
instrumentation is explicitly disabled for ubsan.c.

core: add callout service

Add a callout service to call registered callback functions at a given
time from now. A callout is periodic or oneshot depending on how the
callback function returns. Callback functions execute in nexus and
interrupt context.

The callout service is initialized with callout_service_init() and
depends on an abstract timer interface to manage the hardware timer.
callout_service_cb() needs to be called from the timer interrupt handler
to drive the callout service.

core: kernel: Add semihosting functions

Semihosting is a mechanism that enables target to communicate and use
I/O facilities on a host computer which is running a debugger, such as
GDB. The I/O facilities include character {read|write} {from|to} the
semihosting host side console or a file. In other words, OP-TEE OS can
output log to the host side console or the host side file, if there is a
semihosting host and OP-TEE OS requests the semihosting operations to
that host.

If CFG_SEMIHOSTING is enabled, some semihosting functions will be
compiled into OP-TEE kernel, including:
- semihosting_sys_readc()
- semihosting_sys_writec()
- semihosting_open()
- semihosting_read()
- semihosting_write()
- semihosting_close()

Note that the architectures which support semihosting should provide
their implementation of __do_semihosting(), which performs semihosting
instruction to raise the semihosting request.

To parse the eventlog and extend PCR's device is needed which

supports PCR like registers. Such a device can register itself
as a TCG provider for PCR information and ability to extend the
PCR's.
