RFR: 8319795: Static huge pages are not used for CodeCache

[Evgeny Astigeevich]

This is a fix of a regression introduced by [JDK-8261894](https://bugs.openjdk.org/browse/JDK-8261894).
After JDK-8261894, `os::can_execute_large_page_memory()` returns `true` only if `UseTransparentHugePages` is true. As CodeCache uses `os::can_execute_large_page_memory()` when it detects a page size. CodeCache cannot use static huge pages.
Before JDK-8261894, `os::can_execute_large_page_memory()` returned `true`  when either `UseTransparentHugePages` or `UseHugeTLBFS` was true.

After JDK-8261894, `XX:+UseLargePages XX:-UseTransparentHugePages` means to use static huge pages: aka `UseHugeTLBFS` is `true`. If `UseLargePages` is not set to `true` via the option, it will be set to `true` if `UseTransparentHugePages` is `true`.

`os::can_execute_large_page_memory()` is modified to return `UseLargePages`. A regression gtest  is added.

Tested fastdebug and release builds:
- [x] tier1
- [x] gtest
- [x] test/hotspot/jtreg/gtest/LargePageGtests.java
