fix(esp_phy): Allow WiFi/USB interference workaround option only on supported targets

Browse Source 
"Enable USB when phy init" Kconfig option would call esp_phy function
`phy_bbpll_en_usb()` that is not implemented for all targets.
Selecting this option for unsupported target results in linking error.

The necessity of this workaround is now defined soc_caps.h rather than
in the Kconfig.

Closes https://github.com/espressif/esp-idf/issues/12185

help
When using USB Serial/JTAG/OTG/CDC, PHY should enable USB, otherwise USB module
can not work properly. Notice: Enabling this configuration option will slightly impact wifi performance.
On some ESP targets, the USB PHY can interfere with WiFi thus lowering WiFi performance. As a result, on
those affected ESP targets, the ESP PHY library's initialization will automatically disable the USB PHY to
get best WiFi performance. This option controls whether or not the ESP PHY library will keep the USB PHY
enabled on initialization.
Note: This option can be disabled to increase WiFi performance. However, disabling this option will also
mean that the USB PHY cannot be used while WiFi is enabled.
config ESP_PHY_ENABLE_CERT_TEST
bool "Enable RF certification test functions"
