[corlib] Fix sharing mode validation rules  (mono/mono#16247)

Fixes https://github.com/mono/mono/issues/16032

When we switched to corefx File.Copy on unix, the behavior changed where it opened a source and destination stream in order to pass the safe handles to Interop.Sys.CopyFile. This exposed a flaw in our sharing validation rules in MonoIO.Open, which threw an exception in this scenario:

new FileStream("source.txt", FileMode.OpenOrCreate, FileAccess.ReadWrite, FileShare.ReadWrite, 2048, FileOptions.DeleteOnClose);
new FileStream("source.txt", FileMode.Open, FileAccess.Read, FileShare.Read, 2048, FileOptions.None);

Simplified the FileShare check down to:

1. If the caller specifies FileShare.None, then it's an exclusive lock and no
   sharing is allowed.

2. If the caller specifies some other FileShare option, then FileShare.None
    cannot be specified.

The order is a little tangled but convincing.
The helper function returns MonoException* or checks context->has_resume_state and then returns, and then the caller does the checks again.

Based on past analysis this will conserve stack, but that was not double checked here.
i.e. due to `&valuetype_this`, though it is conditional and the code could be split up into inline and outline.

Replaced instead with a method that eliminates the room for error with methods
that will initialize the whole structure, and the actual size computation is
done inside the method with the proper type sizes.

[runtime] Initialize thread suspend policy at startup, inline getter (mono/mono#16149)

On some benchmarks we saw mono_threads_suspend_policy() using a lot of CPU
time.

Rather than doing an init-on-first-use, initialize the policy once upfront when
the JIT it starting up and make the getter method static inline.

* move mono_threads_suspend_policy_init into mono_thread_info_init

* [mini] Initialize suspend policy for `mono --version`

Need to initialize the suspend policy before printing its name.  Otherwise the
suspend policy is unset since no other runtime initialization is done for `--version`.

[w32process-win32] Don't duplicate CreateProcess search logic. (mono/mono#16156)

When given a null application name, CreateProcess already
searches the path and appends .exe in some cases. .NET's
Process class behaves in the same way (see
https://github.com/mono/mono/pull/16089#issuecomment-519984244).

The duplicated logic is unnecessary and broken in several ways.
Failures are ignored and the command line arguments are
executed. Relative paths are expected not to end in "exe".
Many corner cases work differently from .NET and CreateProcess.

This change makes it impossible for process_complete_path to fail,
so I removed the gboolean return and pulled out the output
parameter. Its caller wasn't handling the return value correctly
anyway.
